  • Got my rings out!

    Early in the pandemic I bought a set of gymnastic rings, started training with them, and got great results. They have a few downsides, though: Since I hang them up outdoors it’s no fun to us them when its cold or wet or windy. Also, the easiest place to hang them up (the basketball court) is kind of out in public. I don’t really mind people watching me workout, but occasionally it’s a little awkward.

    Me at the top of an inverted row using gymnastic rings
    I neglected to get a photo today, but this is pretty much what I looked like.

    Especially during the winter, I’ve largely switched to steel club exercises. I can do them in my study, they’re a similarly good workout. Besides that, they add an element of rotation which I find useful to support my fencing.

    One downside of club (and kettlebell) exercises is that they’re really not practical to do to failure.

    Exercise machines are great to do to failure. With little or no risk of injury, you can know that you’ve gotten the maximum stimulus to strength and hypertrophy. With kettlebells or clubs, training to failure means that a big steel weight goes flying out of your hands and into whatever happens to be in the vicinity—a terrible idea.

    The rings are closer to weight machines. I use them almost exclusively for three different exercises: inverted rows, dips, and pull ups. Do any of them to failure and all that happens is you don’t finish a rep. I suppose actual gymnasts do various sorts of inversions and such, where it might be dangerous to fail a rep. That’s not an issue for me.

    Anyway, this morning I got my rings out, put them up at the basketball court, and did a version of the same circuit I did many times over the past five years. I did three rounds of:

    Jump rope

    This was mainly just to get/keep me warmed up for the rest of the round. I did sets of 100 jumps, and was pleased to find that I could still do them with just one or two misses in a set.

    Inverted rows

    These are a way to work the lats. I’ll hope I can do pull ups again soon, but even then I’ll probably stick to inverted rows for half my lat exercises. I did sets of 8 rows to failure, which is exactly what I was going for.

    Slamball hunter squats

    This exercise comes from Mark Wildman’s slamball program. You powerclean a slamball, do a double-pivot to turn 90 degrees to one side, which leaves you in a stagger stance. Then you drop down to a hunter squat (about mid-way between a squat and a lunge), holding the slamball in front of you. Then you stand back up, double-pivot again to face forward, and drop the slamball. Then you repeat, pivoting the opposite direction.

    I was doing it with a 15 lb slamball, which isn’t terribly heavy, but I was too lazy to carry my heavier slamball out to the basketball court.

    I did sets of 6 to 8 reps (3 or 4 each direction), which isn’t enough to reach failure on my legs. I either need to do more reps or else bite the bullet and bring out the 30 lb slamball.

    Dips

    Somewhat to my surprise, I actually manage to do 1 dip! That was all I managed though, so I satisfied myself with doing negative dips for the rest of my reps. But if I can do 1 dip, being able to do sets of 3 or even 4 is not far off.

    Hollowbody hold

    This was easier than I’d expected, I guess due to the Mark Wildman ab exercise program I’d been doing for a few months now. I did a 45-second hold each round.

    I did a total of three rounds, which is what I did for most of my rings workouts in years past. It felt like a legit good workout.

    I’m thinking two of those workouts per week, plus two club workouts per week, plus two runs per week (a long run and a fast run), would add up to a great, well-rounded exercise routine. Of course, I’ll also want to do a fencing class as well, adding up to seven workouts per week, which is perhaps a bit more than would be wise, but I don’t see any alternative.

  • Fix Social Security by Fixing Society

    I’ve been hearing for years about how much trouble Social Security is in, and how pretty soon there won’t be enough money left in the trust fund to pay everyone’s pensions in full, and how we’ll have to raise taxes or cut benefits. That’s almost entirely false.

    The Greenspan commission that restructured Social Security back in 1983 got almost everything right (which is why we haven’t needed to change Social Security tax rates, diddle around with the cost of living adjustments, nor change the age at which people retire for forty years). The one thing they got wrong?

    Back then, about 90 percent of all wages were subject to Social Security payroll taxes. Today, that’s dropped to around 82.6 percent as more income has shifted above the taxable maximum.

    Source: Actually, Social Security Nailed It In 1983

    The most common suggestion for “fixing” Social Security is to get rid of the ceiling on the amount of income subject to the tax, but that’s the wrong way to think about it. Getting rid of the ceiling would decouple the size of the eventual pension from the size of the income that earned it, which would give conservatives yet another hook for criticizing the program.

    The right fix is to boost incomes of those at the bottom, so that once again 90% of all wages are under the Social Security tax ceiling.

    Making sure that lower-income people earn enough money to live on will fix Social Security as a side-effect.

    Pretty cool, eh?

  • We know what happens when the Fed “looks through” one-off price hikes

    Many politicians and financial analyst types are suggesting that the Fed should “look through” tariff-induced price hikes. Superficially this makes sense, because a one-time cost increase is not the same thing as inflation. Unfortunately, we know that the results are bad.

    The example I’m thinking of is the price shock from much higher oil prices due to the 1973 OPEC oil embargo. As that price shock moved through the economy, first oil prices went up, then gasoline prices went up, but very shortly all prices moved up, because every business faced higher energy costs, and needed to pass at least a fraction of them forward. And then, of course, all the businesses that bought things from those businesses needed to raise their prices further, and workers started demanding higher wages because their costs were going up.

    The Federal Reserve tried to “look through” that price shock, not raising interest rates, even though prices were rising. As I say, this makes sense. The one-time price shock will move through the economy, raising many prices by various amounts (depending on how much the inputs for each particular item increase in cost, and the market constraints on price increases for each particular item). Once that all works through the economy, the prices increases should stop.

    In fact, raising interest rates could easily make things worse, because the cost of credit is another cost to nearly all businesses, so it’s just another expense that they have to pass on, and it’s a cost to employees, that they’ll want to recover in wage negotiations.

    But we know what happened: Inflation rose enough that the Fed eventually decided that it needed to raise interest rates. Higher interest rates hurt the economy, threatening to produce a recession. The Fed cut interest rates to head off the threatened recession, which led to inflation, which led to the Fed raising rates again, etc.

    The result was the stagflation of the 1970s, which only ended when new Fed chairman Paul Volker raised rates high enough to produce a severe recession, and then kept them high for long enough to wring the inflation out of the economy.

    To me it’s clear that “looking through” the “one-time” price shock of higher tariffs will produce the same result. The Fed can probably mitigate it by holding rates at their current levels until the price shock works its way through the economy (which will probably take a least a year, because many prices (wages, rents, etc.) are only renegotiated annually), and only cut rates after price increases settle back down to close to the Fed’s 2% target.

    I assume the Fed governors know this. Do they have the courage to take the right action? Only time will tell.

  • My happenstantial daily routine

    For years I worried a lot about daily routines. (Just click on the tag for “daily routine” and you can find literally dozens of posts on the topic.) Of late, that seems to no longer be the case. It’s been years since I posted on the topic.

    A few days ago though, my brother mentioned me in a toot on daily routines, which prompted me to wonder what my current daily routine actually looks like. Turns out, I do have a daily routine, that I stick to pretty well (with minor adjustments for errands, medical appointments, etc.).

    Unsurprisingly, it’s rather sun-aligned.

    Sunrise through thin clouds viewed across Dohme Park

    (6:00 AM) I get up around dawn, which is at different times at different parts of the year, but is around 6:00 AM right now. I drink a (ginormous) mug of coffee (or two). I spend some time dicking around on the internet, check my social media feeds, chat on-line with my brother, and get an update on our mom (who lives with him). I also check my Oura ring, to see how well I slept. (That’s a joke. Of course I know how well I slept. But the information my Oura ring provides is nevertheless sometimes valuable.) We usually do the Jumble via chat during this time as well.

    (6:40 AM) Around sunrise I take the dog for her first walk of the day. That’s been around 6:45 lately, but is getting earlier every day just now.

    (7:00 AM) After first-walk I might have a third cup of coffee, but I proceed to fixing and then eating breakfast.

    (8:00 AM) After breakfast it’s time for the dog’s second walk. This is the long walk of the day. In bad weather it might also be just 20 minutes, but is usually at least 40 minutes, and in really nice weather might be an 90 minutes or longer.)

    (9:00 AM) Once I get home from second walk, I proceed to my morning exercises, which I ought to be able to do in 20 minutes or so, but which often stretches out to twice that long. I’m working to shorten it, so I have some hope of getting something else done during the day.

    (9:30 AM) After morning exercises (which is really a stretching/flexibility/mobility routine), I proceed to my workout, unless it’s a rest day. That takes 40 minutes to an hour.

    Since I started drafting this post three or four days ago, I’ve been tracking the start and end times of my morning exercises and my workouts, with an eye toward collapsing the total time for this stuff down to the 60–80 minutes that it should be. If I can do that, I should be able to finish no later than 10:30, which should give me most of three hours available to get work done, before I need to break for the main meal of the day.

    (10:30 AM) Get work done!

    (1:00 PM) Jackie and I have moved our main meal of the day to 1:00 PM or 2:00 PM, which provides just a bit more flexibility for getting work done in the morning (although that time gets used up if I need to run an errand, or if I’m fixing lunch that day). Ashley usually gets her third walk of the day either right before or right after lunch.

    I generally don’t even try to get anything useful done after that. I might take a nap. I might read. I might spend some more time dicking around on the internet. Just lately, I’ve been trying to get a backup server configured so that my brother and I can backup our backups to each other’s servers, meaning that we’ll have off-site backups.

    (4:15 PM) At 4:15 PM we have our cocktail hour call with Steven and my mom. We’ve all cut back on alcohol consumption, so we usually drink water rather than a cocktail, but we’re sticking with the call. It means I get to talk to my mom nearly every day.

    (4:45 PM) After cocktail hour I take Ashley for her fourth (and now, finally, last) walk of the day. When she was a puppy I had to take her for eight walks a day (to keep her from peeing in the floor). That ramped down pretty quickly to seven and then six, but it took a long time to get her down to five and then four. But this is actually much more convenient for me, as well as being enough walking for both of us. (I average over 12,000 steps a day, even in the winter. In the summer it’s more like 15,000.)

    (5:30 PM) After fourth-walk I usually sit down to watch some video entertainment with Jackie, or else read some more.

    Jackie goes to bed quite early most days, a remnant from her days working at the bakery (when she had to get up at 4:00 AM).

    I generally like to go to bed a couple of hours after sunset, although not that early in mid-winter nor that late in high summer. Just lately I’ve been aiming to take Ashley out of the patio for one last peeing opportunity in time for me to get to bed around 9:00 PM.

    There’s some variability, of course. Mondays I do Esperanto in the early evening. Wednesdays there’s (just recently) a gentlemen’s lunch. Thursdays there lunch with some former coworkers, that’s been going on in some form or another for decades now. Sunday afternoons (and when I’m feeling fit enough, Tuesday and Thursday evenings) there’s sword fighting.

    As I said above, the main value of this post to me seems to be around how I might get my warmup and workout done more compactly. I think I’ll write about that soon, and if I do, I’ll link to it here.

  • Sensible sleep (with an Oura ring)

    Several times in my adult life I have suffered a bout of very poor sleep, usually due to life stress. One of those times, six years ago, coincided with the Oura ring becoming available. So I bought one.

    Buying a ring, of course, doesn’t help you sleep better. The Oura ring just offers metrics on your sleep. It’s up to you to make sensible use of that data.

    Besides buying the ring, I went down the rabbit hole of reading about sleep. In particular, I read the book Why We Sleep by Matthew Walker. Based on that book, and a lot of reading of internet articles on sleep, I started trying to get 8 hours of sleep a night, as measured by my Oura ring.

    Of course that’s not what the “8 hours of sleep” number ever was. The number was always a “time in bed” number, assuming that you spent an average fraction of that time actually asleep. (Some people might actually need 8 hours of actual sleep per night, but that’s not what the number referred to.)

    I conducted various experiments (which is what the Oura ring makes possible), but about the only way I could get 8 hours of actual sleep (besides being really, really tired) was to spend 10 or more hours in bed. Rather pleasant on the right sort of day when you’re in the right sort of mood, but not really a practical lifestyle, even for someone like me who doesn’t need to go work a regular job any more.

    I did the sensible thing, which was to mostly not worry about it, and just try to get plenty of sleep. And I did okay. My average sleep score from my Oura ring over the 6+ years I’ve had it has been 84. (That’s one tick below the cut-off for “excellent” sleep.)

    Just lately though, I’ve made another tweak to my “sensible sleep” strategy (which will no doubt seem extremely obvious to anyone who has never had an extended period of very bad sleep): I quit trying to extend my time in bed in an effort to try and get 7 or 8 hours of actual sleep.

    Like all sensible people, I’m back to just going to bed when I feel sleepy, and getting up when I wake up feeling refreshed.

    My Oura ring likes the results:

    Oura ring graphic showing a sleep score of 90
    Oura ring graphic showing a readiness score of 90

    In part this was due to hearing an interview with the author of How to Sleep Like a Caveman by Merijn van de Laar. He reports that Hadza people spend a very typical amount of time in bed, but only spend a little over six and a half hours of that time asleep.

    Of course the smart thing to do is to go entirely by feel: If you wake up feeling refreshed, you’re probably getting enough sleep. If you get sleepy during the day, maybe take a nap.

    The Oura ring is for when that simple, sensible strategy doesn’t do the trick.

  • Intuitive rest days

    For most of my adult life, trying to use “intuition” to decide on rest days would have been a terrible idea. If I’d let myself say, “Hmm. I don’t really feel like a workout today,” I’d scarcely have worked out at all. Instead, I came up with a schedule, and stuck to it, either well or poorly.

    When I stuck to it well, I’d see progress. When I stuck to it poorly, I wouldn’t.

    Starting around 5 years ago or so, something changed in my brain: I started really enjoying my workouts.

    Partially, it was that they were working well, which is just satisfying. But it was more than that. First, I noticed that I felt better after a workout. Then I started feeling better during a workout. Instead of it being hard to motivate myself to work out, I craved workouts.

    People who knew me were mildly disturbed by this. It was unlike me. It was certainly unlike them. I would not be surprised if they began to suspect that I was some sort of pod-person.

    Because I wanted to work out nearly every day, I would sometimes wonder if I was over-training (or under-recovering), but that’s not trivially easy to determine in the moment.

    I’ve long tracked my workouts, but not really in a consistent way—I’d just write down what I did that day. Sometimes I could look back and say, “Wow. That looks like a serious workout,” and other times I’d look back and say, “Was that really a workout?” But often times it wasn’t clear either way.

    Just lately though, I’ve been doing the Mark Wildman workout programs that I mentioned a few weeks ago. That gives me a pretty consistent metric. I’m doing three different programs, each of which has 4 to 7 different levels, each of which can be done with an almost infinite range of weights, but they all have a consistency in design: start with a light weight, work up in complexity, then bump up the weight but go back down in complexity. If you’re consciously attempting to make progress, then it’s pretty easy to make each workout “count” as a workout, while avoiding overdoing it in any particular workout.

    Me in a hunter's squat holding a 40 lb slamball

    But while avoiding overdoing it in any particular workout is good, it is possible to do that, and yet get over-trained, simply by doing too many workouts with inadequate recovery.

    So, today I went back over my past 3 months’ training log entries. For my first cut at this, I’m just counting rest days. I figure that I want to work out either 5 or 6 days a week, which makes any week where I have either 1 or 2 rest days a “good” week.

    In the past 13 weeks I’ve had 1 week with 0 rest days, 1 week with 3 rest days, and 1 week with 4 rest days. All the rest were “good” weeks with either 1 or 2 rest days.

    That’s just about perfect. The usual advice is to take a “deload” week every 4 to 6 weeks, so 2 weeks out of 13 being weeks with extra rest just about hits the nail on the head. The one week with 0 rest days was probably just an artifact of rest days falling outside of one calendar week—not a big deal, as long as it’s rare.

    Anyway, the intuitive rest days seem to be working well. I’m getting in my workouts, and I’m getting in adequate rest. I guess I can stick with it for a while.

  • Our new upcoming stagflation

    A group of friends and I agreed last week that the most likely result of the most likely policies coming out of this administration is stagflation.

    Plaque for the Northern Trust Company

    Talking about it reminded me of the Wise Bread post I wrote All about stagflation, so I re-read that. I think has held up pretty well, even though circumstances (financial crisis followed by a pandemic) meant that things didn’t play out as I’d expected. Even so, I think the analysis of how to produce a stagflation is right on: raise interest rates to bring down inflation, but then panic when it’s clear that you’re in danger of producing a recession and cut rates before you’ve gotten inflation under control; repeat until you have high inflation and a recession.

    That is, stagflation is usually the result of a timid Fed, that’s afraid to do its job.

    The thing is, the policies that I see coming (tariffs and tax cuts) will produce stagflation even if the Fed does a great job. The tariffs directly raise prices, and the tax cuts (through increased deficits) raise interest rates, producing a recession.

    In the Wise Bread article I warn that it’s tough to position your investments for stagflation. The reason is that inflation makes the money worth less (helping people with debts, but hurting people with money), while the recession hurts people with debts and people with investments.

    Upon reflection though, I don’t think it’s quite that bad. In fact, it’s really just regular good financial advice:

    1. Avoid debt (you’ll get crushed by a recession faster than you’ll get rescued by inflation).
    2. To the extent that you have assets, move them into cash (initially you’ll get screwed by inflation, but pretty soon rising interest rates will save you).
    3. Limit your investments in stocks, and especially limit your investments in your own business (both much too likely to get crushed by recession).

    Basically: live within your means and stay liquid.

  • Struggling with Schadenfreude

    I don’t think of myself as someone who wishes ill for others. I genuinely do not wish for anyone to come to harm. But I’m struggling just a bit with schadenfreude right now.

    Take, as an example, the wildfires in California. As I mentioned a couple of weeks ago, these fire events were not just entirely foreseeable; they were actually foreseen forty years ago. And yet, there are tens of thousands of people who apparently made the calculation that the views from a house on a hillside at the urban-chaparral interface were so good it was worth taking the risk—and especially so, given that a large fraction of the costs of fighting those fires, and insuring against financial loss, could be spread to other people. People like me.

    I think I’m allowed a bit of, “I hope you are enjoying the entirely foreseeable consequences of your choices.”

    As another example, take the snow about to hit New Orleans:

    By Tuesday, the winter storm will drop freezing rain, sleet and likely several inches of snow onto south Louisiana, including in New Orleans, Metairie, Slidell, Baton Rouge and Lafayette.

    I have to admit that when people in red states face an extreme weather event that’s entirely to be expected, a certain part of me thinks, “Well, you could have voted for politicians and policies that would have greatly ameliorated climate change, but you didn’t. Enjoy the entirely foreseeable consequences of those choices.”

    And, as a non-climate example, apparently a lot of black and brown male voters refused to vote for Kamala Harris. I suspect many of them will be surprised and saddened by the utterly predictable deportations of friends, family members, neighbors, coworkers, and employees over the next few years. And I will be very sad about that—sad for the people deported and their friends and family, and also about the dreadful police actions that will be required to make them happen. But I hope I will be excused from feeling no sympathy for the bosses who find themselves having to pay up to get workers who haven’t been deported, and very little sympathy for the people who voted for these policies and find that everything they want to buy costs more.

    “Welcome to the entirely foreseeable consequences of your actions as well.”

  • Zone 2 cardio for the non-anal

    Zone-2 cardio has been having its moment. That comes from a lot of sources, but unfortunately a big one is Peter Attia. I say “unfortunately,” because Attia seems to have a weird, compulsive sense that zone-2 cardio work needs to be, I don’t know, pure in some way, rather than just being enough to promote good metabolic health.

    Attia suggests that you do your zone-2 work on a treadmill, stationary bike, or rowing machine, so you can be in control of your effort level at all times. Then you can just get into zone 2 and stay there for 45 minutes.

    I think this is crazy, and not just because 45 minutes of steady-state activity on a treadmill or stationary bike would be excruciatingly boring.

    I do my zone-2 cardio with a mixture of walking my dog, running and occasional hikes. Walking the dog isn’t perfect, because the dog keeps stopping to get in her sniffies, and no doubt my heart rate drops out of zone 2. Running isn’t great, because my heart rate probably spends a lot of time in zone 3 or zone 4. A lot of it is zone-2—at least, I can talk while I run, which is one of the tests for zone-2. (I run very slowly.) The hikes are probably perfect zone-2 cardio, but are a big time commitment in a single day.

    Attia suggests that you optimize your cardio workouts by getting 3 hours a week of zone-2 cardio, which can optionally be divided into 4 45-minute workouts. And I’m sure that’s fine. But I suspect that getting in a couple of runs a week, along with a good bit of dog walking, is going to check the zone-2 cardio box no problem.

    My theory (and I am not an MD, nor even a PhD in exercise physiology, but still) is that this is fine. You don’t need to get 45 minutes of pure zone-2 cardio to be metabolically healthy.

    As I see it, the test for whether you’re getting enough zone-2 cardio is whether or not you can engage in a moderate level of exercise for an extended period—a 3-hour hike, let’s say. If you’re metabolically healthy you can go on and on at a moderate pace, because you’re doing it almost entirely aerobically.

    Me on the Ham's Bluff Lighthouse trail on St Croix

    If you can do that, you’re getting enough zone-2 cardio, regardless of whether your sessions are 45 minutes long, and regardless of whether they add up to 3 hours a week. If you’re not metabolically healthy, even going at a moderate pace is going to push you into anaerobic metabolism, which will quickly become impossible to maintain.

    It probably is true that you need to get in 3 hours a week if you’re going to be able to go on long, long hikes. But the idea that they need to be pure zone-2 sessions, rather than mixed sessions at all different levels of intensity, is just crazy.

  • Moving back toward movement

    About a decade ago, thanks especially to finding the work of Katy Bowman, but also from taking an interest in parkour and similar disciplines, I came to realize that movement was a better model for healthy activity than exercise.

    Then came the pandemic.

    For a lot of reasons—in particular, the loss of the opportunity for moving with a community—I found that returning to exercise suited me better, especially in the early days of the pandemic. (Follow that link for a pretty good post about where training falls on the movement vs. exercise spectrum.)

    Over the past year I realized that it’s been five years now that I’ve prioritized exercise over movement, despite the fact that I still think that movement is the better choice. But when I started thinking that I should start trying to emphasize movement more again, I realized I already have been.

    The biggest way that movement has snuck back into my practice is HEMA (aka sword fighting). There is some exercise involved in training for sword fighting, and it is certainly not a complete healthy movement practice all on its own, but it is moving, for a purpose, with a community—things I had been lacking for years.

    The next biggest has been walking. In particular, dog walking. It’s not that walking has snuck back into my practice. I have always been a walker, and all that getting a dog changed was that now I walk every single day, instead of merely almost every day. (Even during bad weather, I average at least 12,000 steps per day. When the weather is nice, I top 15,000.) What having a dog changes is that now the walking is not exercise. It’s movement, because I’m doing it for a purpose that has nothing to do with “getting some exercise,” and rather is about making sure my dog is getting what she needs.

    I still do some exercise. In particular, I’ve paid up for four workout programs by Mark Wildman: His two club programs two-handed and one-handed, his slamball program, and his “actual action hero” ab program. I skipped getting a kettlebell program (I’ve been doing kettlebells long enough that I feel like I know how to integrate them into a fitness routine, plus my sore elbow seems to be aggravated more by kettlebell moves than by club or slamball moves.)

    I’m really pleased with the two-handed club program, which adds to the basic swinging moves a set of lunge moves, a set of squat moves, and a set of ab moves (that work toward a get-up).

    Me doing a lunge with a heavy club
    Me doing a balance squat with a heavy club

    The one-handed club program is also good, but much more technical and specific. It’s purpose, I guess, is to improve your alignment and structure, which is cool (and which I expect will be useful for sword fighting), but it doesn’t look like it’s going to do a lot for overall fitness.

    The ab program is interesting. Mark Wildman wrote it for his friends who are stunt people, who needed a program that could be done in a very small space (basically a yoga mat on the floor of a trailer, which is what stunt people live in on-set), that focused not on making your abs look good (although it definitely will) but rather on building the muscle, strength, and control to do the sorts of moves that stunt people need to do. It’s designed to be done in just a few minutes every day at the end of your usual workout. It has 50 moves, and it gives you a different combination of them every day for up to a year (assuming you can work up to doing continuous ab work for 14 minutes a day, five days a week.

    Me doing a crab cross-touch

    So, I do continue to exercise, because it seems useful, and it suits me, but I’m going to resume trying to prioritize movement going forward.

  • Libertarians, crypto-bros, tech-bros, and incels

    Playboy magazine and Helen Gurley Brown. That’s what last week’s New York Times opinion piece, Barstool Conservatism, Revisited (on the weird agglomeration of libertarians, crypto- and tech- bros, and incels who ended up voting with social conservatives) made me think of.

    My thoughts draw on a book I read about Hugh Hefner, Playboy, and Helen Gurley Brown. The basic thesis, as I recall it, was that Hefner wanted a society where young men could enjoy an extended youth. The best way to make that work, he thought, was for women to be able to support themselves—so that they’d be willing to sleep with men, rather than feeling that they had to hold out for a man who would marry them.

    To that end, Playboy magazine was very active at promoting equal rights for women—so they could earn money, own property, etc. Because only when they were able to support themselves without needing to get married, would they be willing to sleep around. And women willing to sleep around, were what the Playboy demographic wanted.

    That social experiment played out pretty much just the way Hefner wanted through most of the 1960s, 1970s, and 1980s. Women could earn enough to afford an apartment, food, clothing, and the other necessities, which meant that they didn’t have to get married just to survive.

    However (and this was key, even though I don’t think Hefner really thought about it much) men earned more than women.

    The result was perfect for men. They had enough money to buy fancy cars, fancy stereos, fancy watches, expensive liquor—all the sorts of products that advertised in Playboy—with enough left over that they could afford to take women out on nice dates and buy them little gifts. The women earned enough less that, although they could get by, they couldn’t have really nice things, except when men bought them.

    Things began to change the 1990s, when women’s incomes grew to the point that they could afford nice things. That produced two changes. First, women that could afford not merely a tiny apartment, but their own house, weren’t so reliant on men to make them comfortable. Second, with so many women taking top jobs, there were fewer top jobs for men. That meant that more and more men found it tough to earn an income that let them improve a woman’s standard of living.

    This situation is what has the incels so unhappy. For decades, even after women weren’t legally subservient to men, men generally had enough money that they had something very tangible to offer a woman. Now that’s only true for the top few percent of male wage earners.

    Of course, any man with either ambition or good sense could work around this situation. Becoming one of the 1% is hard, but simply having enough ambition to get into, let’s say, the top 50%, means that you have enough of a surplus to be able to raise the standard of living of a woman. And good sense is all it takes to do a bit of an analysis and realize that following the strategies of the pick-up bros isn’t going to lead to what you want nearly as well as coming up with things to offer to women besides cash. (Different things for different women, but: getting fit, wearing nice clothes, learning about the arts or science or history—whatever any particular woman is interested in, paying attention to them when they talk, being supportive of their efforts, are all things that might work.)

    But incels as a group don’t seem to want to make even that modicum of an effort. They’d rather blame women.

    The other groups I mentioned are broadly similar. Even the rich, successful tech bros are often dysfunctional to the point that they have trouble attracting women. Libertarians are often attracted to the movement specifically because what they yearn for is a world where people have minimal legal protections from the wealthy (and for no good reason, they imagine that they’ll be wealthy enough to take advantage of that). Crypto bros are the same, except they have a specific (rather than vague) notion of where their money is going to come from, even if it’s a fantasy.

    So I understand that article. I think that is why all those disparate groups came together, even when their actual interests are pretty disparate.

    The big question is, will these groups hang together going forward? Or will the fact that they have nothing much in common except a fantasy of enjoying being on top, lead to infighting and failure?

    I’m hoping for failure, but it’s still too soon to say.

  • A walkable dog 🐕‍🦺

    Jackie walked Ashley successfully for a couple of days right after we brought her home from the shelter, but then we had a couple of incidents where the dog pulled her over, or yanked the leash out of her hand, and we realized that it wasn’t safe for Jackie to be the dog walker.

    A black dog with a white chest lying on the sofa, looking toward the camera

    Over the past couple of years though, Ashley has gradually become more tractable, and today we decided to experiment once again with Jackie being the dog walker.

    It worked great! Ashley pulled some, but I don’t think Jackie was ever in danger of being pulled over, or of losing the leash.

    We were thinking of it especially because tomorrow I’m going to spend close to 10 hours at an all-day sword fighting workshop organized by my local club TMHF, which is bringing in three well-known HEMA instructors to teach classes. There’s a group lunch, but I’m going to have to miss it to dash home and walk the dog. But since this outing went so well, hopefully next time there’s something like this, Jackie will be able to do the dog walking. It’s also a useful backup, just in case I’m sick or injured, to have Jackie able to do what’s necessary.

  • Fancy-dress fencing

    I’ve scarcely fenced with the students since the groups split a year ago. It was made clear that I was welcome to come train with the student group, but most of the training sessions were the same time as my group was meeting, and anyway my shoulder and elbow issues meant I had to reduce the amount of training I was doing, so I ended up training with my own group.

    That changed this week when the student group had a “fancy-dress fechtschule,” and invited the TMHF members to join in.

    A fechtschule (which just means “fight school”) is a particular kind of contest where the point is not so much to “win” (although you want to do that too), as it is to display artful fencing. To encourage that the rules call for only head hits to count, and prohibit things like thrusting (too likely kill your opponent), grappling, pommel strikes, etc.

    Because only head hits count, it seemed reasonably safe to wear just masks and not full protective gear, enabling a fancy-dress version, which seemed to me like great fun. Many of the women showed up in dresses or gowns of one sort or another (some in heels!). Many of the men wore suits. I wore a coat and tie.

    The call for attending was simply to wear “the most formal thing you own that you are willing to fight in.”

    After a youth during which I couldn’t imagine “dressing up” any more than absolutely necessary, somewhere along the line I figured out a few things, one of which was that men’s dress clothing is actually more comfortable than casual clothing, because it is altered to fit well, rather than just being “the right size.” These days besides wearing dress clothing whenever it will give me an advantage, I also wear it anytime it seems like fun. (While traveling—on a plane or a train, and while in a station or an airport—you get much better service if you’re wearing a coat and tie than if you’re wearing shorts or sweats.)

    There was a great deal of artful fencing.

    It has taken most of three years, but I’m finally doing a pretty good job of keeping my arms extended while doing longsword. (Partly I just needed to develop the habit, but I also needed to build strength and endurance in that arms-extended posture.)

    It was glorious fun. I even did okay in the contest. (I think Milosh went easy on me.)

    I do need more work on fencing artfully.

  • Inflation and interest rates in 2025 and beyond

    Let me start by saying that, judging from his previous term, most of what the incoming president says has no particular bearing on what he’s going to do. But I think a few trends look likely enough that it’s worth thinking about the results on the dollar’s value.

    The things I’m thinking of are tariffs and tax cuts, which I expect to lead to higher inflation and larger deficits, both of which will lead to higher interest rates.

    Graph of inflation rate and 3-month t-bill rate going back to June of 1977 (when I graduated from high school
    Blue is the historical Inflation rate (CPI vs one year earlier). Red is the historical 3-month T-bill rate (roughly what you could earn in a money market fund). Both are from June, 1977 (when I graduated from high school) through last month.

    Tariffs

    The president can impose tariffs on his own, with no need for congressional action. Whether we’ll get the proposed 60% tariffs on Chinese goods, or whether that’s just a bargaining chip, I have no idea. But I think some amount of tariff increase will be imposed, which will feed through directly to higher prices.

    That’s not to say that tariffs are necessarily bad (although usually they are). But they do feed through to higher prices.

    Tax cuts

    Tax cuts need to get through Congress. If the Republicans get the House as well as the Senate, it’s highly likely that legislation will preserve the 2017 tax cuts set to expire next year, and probably some additional tax cuts, such as a much lower rate on corporate income. It’s also possible that we’ll see the proposals to cut tax rates on tip income and on overtime pay enacted, although I doubt it. (The incoming president only cares about his own taxes, not about those of random working-class folks.)

    The main thing taxes cuts will do is dramatically increase the deficit. The tariffs will bring in some countervailing revenue, but not nearly enough to fill the gap.

    Other things that raise inflation and cut revenue

    There are all kinds of other proposals that were bandied about during the campaign, such as deporting millions of immigrants, that raise costs both for the government, leading to higher deficits (the labor and logistics both cost money, and not a little) and for employers (they’re employing the immigrants because their wages are lower), which they will try to offset with higher prices.

    What this means for our money

    Rising costs will feed directly into higher prices, which is going to look like inflation to the Fed, so I think we can expect short-term interest rates (the ones controlled by the Fed) to get stuck as a higher level than we’d otherwise have seen.

    At the same time, lower taxes will mean lower government revenues, leading to larger deficits. For years now, the government has been able to get away with rising deficits, but I doubt if the next administration will have as much success in this area. (Why not deserves a post of its own.)

    My expectation is that higher deficits will mean higher long-term interest rates, as Treasury buyers insist on higher rates to reward the risks that they’re taking.

    So: Higher short rates and higher long rates, along with higher inflation.

    What to do

    I had already been expecting inflation rates to stick higher than the market has been expecting, so I’d been looking at investing in TIPS (treasury securities whose value is adjusted for inflation). I’m still planning on doing so, but not with as much money as I’d been thinking of, for two reasons.

    First, I’d been assuming that money market rates would come down, as the Fed lowered short-term rates. Now that I think short-term rates won’t come down as much or as fast, I’m thinking I can just keep more money in cash, and still earn a reasonable return.

    Second, I’d been assuming that treasury securities would definitely pay out—the U.S. has been good for its debts since Alexander Hamilton was the Treasury Secretary. But the incoming president has very odd ideas about bankruptcy. As near as I can tell, he figures the smart move is to borrow as much as possible, and then declare bankruptcy, and then do it again. It worked for him, over and over again. I’m betting that Congress won’t go along with making the United States do the same, but I’m not sure of it.

    Of course, if the United States does do that, the whole economy will go down, and my TIPS not getting paid will be the least of my problems.

  • Cautious Halloween

    Halloween is one of my two favorite holidays (the other being Groundhog’s Day), but last year we had a slight mishap: The kids who knocked on our door had already opened the screen door, so when I opened the door, Ashley ran outside and chased the kids around.

    She was really just doing zoomies, but the little kids were very reasonably terrified to be chased by a dog.

    So this year we’re not going to open our door. But we will be giving out candy. There’ll be a bag on our doorstep, with this sign on the door itself.

    I’ll put it out at 5:00 PM or so, and then do my best to remember not to open the door until trick-or-treating time is over.

  • Wanted: Sandbox for commercial apps

    It seems like every business now has its own app, which usually offers remote ordering, as well as discounts. I do my best not to use any of them, because they demand (and transmit to the business) all sorts of private information from my phone. This seems to me like something my phone ought to fix.

    Front screen of my phone, showing folders of the apps I use

    It ought to be pretty easy on the phone to provide a virtual machine which only passes to an app whatever information the phone owner wants to pass on. For example, you could configure a video loop to provide, if the app wants to turn on the camera, or an audio file to provide if the app wants to turn on the microphone.

    You could get quite fancy about things like location, if you wanted to. For example, a fast food app could be provided a random location, but one that was a configurable distance from the fast food restaurant. (I’m imagining that the fast food apps either already do, or soon will, adjust the price based on where you are. For example, if you’re already in the parking lot, they can raise the price, assuming that you’ve already decided to buy from them. They can cut the price if a competitor is closer to your location, to reduce the chance that you’ll stop there instead. The phone could pick a location to maximize your discount, to the extent that people had been able to figure out and share the algorithm.)

    These sorts of tweaks would be easy to implement, but there’s no functionality in phones to provide them. It’s as if the manufacturers of the phones want to rat you out to every business with a phone app.

    I resist by strictly limiting which apps I install on my phone. But I’d be a lot happier with a virtual machine which would put me in control of what data about me those installed apps could get.

  • Lose weight by exercising more?

    For much of my life I thought that the key to losing weight was just exercising more. Especially in the mid-1980s, when I lived in Utah and California, I’d get out for some long hikes in the mountains and deserts and think, “If I could just do this all the time, it would be easy to maintain a proper weight.” That turns out to be both true and false.

    The fitness influencer types like to say things along the lines of “You can’t outrun your fork,” meaning that you simply can’t burn enough calories to get ahead of eating way too much. I knew that wasn’t completely true. Read about any long-distance endurance athlete (ultra-marathoner, Tour de France rider, etc.) and you’ll have a window into really extreme efforts to eat enough just to keep going, let alone enough to recover for the next day’s effort.

    I also have a slightly more ordinary example. A couple of guys I knew tried to bicycle around Lake Superior and Lake Michigan, and had to abandon the effort halfway through, because their riding (100+ miles per day) burned so many calories (perhaps 5000 calories on top of their basal metabolic rate, so maybe 7500 calories per day total), they ran out of money for food.

    It’s tough to eat 7500 calories per day even without the financial limit, so it seems like, if you have all day to do nothing but exercise, and the will to exercise hard for several hours a day, perhaps you could “outrun your fork.”

    Recent research shows that this is not the case, except in the very short term. People who are very active all day, like hunter-gatherers (but also subsistence farmers, and laborers of other sorts), burn more calories than people who are sedentary all day, but only modestly more.

    A recent study showed that among of Hadza people, activity was almost insignificant as a predictor of total energy expenditure. They were remarkably active, but their calorie consumption was pretty ordinary. The study suggests that body size is just about all that matters

    In that study, average total energy expenditure among Hadza men was 2649 calories per day. The average is higher among western men, but only because their body size is greater. (Hadza men averaged 50.9 kg (112 lbs), while Western men averaged 81.0 kg (179 lbs). Differences in BMI are more stark, with Hadza men having a BMI averaging 20.3, while Western men’s BMIs averaged 25.6.)

    The point here is that it seems like your biology is attuned to wanting to eat 2600 calories and wanting to burn 2600 calories. (Adjust for frame size. It seems the Hadza men averaged about 5′ 2″.) You can be sedentary, under-eat to match, and not gain weight, but it’s not in tune with what you’re body wants, so you’ll be hungry all the time, as well as having all the side-effects of under-movement.

    You can also try to exercise enough to burn more than 2600 calories, but it seems that as soon as you go over that level, your body starts trying to compensate—turning down whatever is easy to turn down, such as your immune system, and muscle-building system.

    That doesn’t happen immediately. If you go on a century ride you will burn the extra 5000 calories that simple arithmetic would suggest. That would probably continue if you went on a three-day bicycle tour. But pretty quickly—probably just in a week or so—less-essential body functions would ramp down (and of course fatigue would ramp up) bringing your total consumption back down toward 2600 calories.

    You can see how this would work well for hunters. You go for a hunt one day (or two or three days), hiking or running for miles, finding prey, tracking it, and finally killing it. Then you (and your whole tribe) have lots of food to eat for a day (or two or three). During extended periods of excess activity maybe your immune system and muscle-building system ramps down, but then during periods of ample food and less activity, maybe it ramps up extra, allowing for full recovery.

    Consuming more calories than you burn for more than a few days, however, quickly leads to problems. Increased fat storage is probably the least of them. Insulin resistance is another. Systemic inflammation is another. Those extra calories will go into the things that get turned down when you’re extra-active, such as the immune system. I don’t know that there’s any evidence, but an obvious possibility is that a lot of auto-immune disorders are just an immune system that never gets turned down because people are never active enough to burn more calories than they eat, if only for a day or two.

    I think it’s true that you can’t out-exercise excess calorie consumption. However, you can definitely under-exercise—and trying to under-eat to match that will also cause problems. Humans evolved to thrive with an ideal level of activity.

    It’s also true that you don’t need to hit that particular level of activity and food consumption every day. In fact, I’m sure you’d be better off to be moderately active most days, and then very active 1–3 days a week. My long-ago dream of being able to hike 10–15 miles every day and then eat all I want turns out to be a terrible idea. Rather, you want to walk 5 or 6 miles most days, and then hike 10–15 miles just once or twice a week. (Feel free to swap in bicycling or rowing or whatever you like for the long days of vigorous activity, although you probably want to keep in the basic walking if you possibly can.)

  • Helene isn’t some unpredictable catastrophe

    I don’t get why people are treating Helene like some unpredictable catastrophe, rather than just the way things are now.

    I’m like, “Hey, it’s going to be like this all the time from now on—either impending disaster, disaster occurring, trying to rescue people from the disaster, or recovering from disaster—from now on.”

    It’s weird that people don’t understand that. I mean, it’s so obvious to me, but people are still treating each new disaster as an unpredictable one-off.

    Although some people are getting a clue. Zillow, for example, will now show climate risks for property listings in the US.

  • Recovering from exercise

    For years now, I’ve been trying to figure out (and writing about figuring out) how to exercise in ways that support all the different things I want to do. My latest hobby, HEMA (sword fighting), has seemed like it required more support than most of my other activities, which prompted more (and more different) exercise than I’d been doing before. I’ve worried for a while that I was overdoing it, and I’m now pretty sure that’s been true.

    Me in fencing jacket and mask with a longsword

    The specific experiment that convinced me was skipping a few HEMA practice sessions. My HEMA club has two-hour practice sessions on Sunday, Tuesday, and Thursday. Two weeks ago I just wasn’t feeling it on Tuesday, and then again on Thursday. Each of those two days I skipped practice, but otherwise did my regular workouts—and started feeling more energetic each day. Last week I repeated that. Not only did I continue to feel better, I also was able to step up my regular workouts a bit.

    I’ve had two specific issues: a sore elbow and a sore neck.

    I’m pretty sure the sore elbow is not HEMA-related, but rather dog-walking related. I think I’ve fixed the issue with how I was handling the dog, but my elbow has been slow to recover—probably because of either how I was handling my longsword, or else how I was exercising to support my longsword training. Having taking a break from longsword training (just going on Sundays, when we’ve been doing rapier training), and having my elbow get much better, even while I continued doing the rest of my exercise regimen, I’m pretty sure it was the actual longsword training that was keeping my elbow from getting better. As I write this, it’s feeling entirely better.

    The sore neck, I suspect, is also HEMA-related, I think due to the asymmetrical stance of longsword. (Rapier stance is even more asymmetrical, but I haven’t been doing it as long or as vigorously.) Anyway, after a couple weeks of less training, my neck was, and is, feeling much better.

    Of course I’m doing all the regular stuff to enhance recovery: stretching, good diet, trying to get plenty of sleep, etc.

    I’m still working toward a plan for exercise. My current thinking is to give up one of Tuesday or Thursday HEMA practice. Then I’ll do four days a week of general exercise focused on support for my HEMA activities: Specifically, I’ve started two different programs of steel club swinging, one 1-handed and the other 2-handed, with a plan to do each of those two days a week. That would add up to 4 days a week. Add to that 2 days a week for HEMA training, and I’d be exercising 6 days a week, with one day of complete rest.

    No one day of that should be completely exhausting, so maybe I’ll be able to recover better than I have been.

  • Newsletter mis-feature on micro.blog

    I use micro.blog to send out my newsletter. I’m generally pretty happy with its newsletter system, but it does have a serious mis-feature: There’s a very narrow window for editing the newsletter between when it generates it, and when when it sends it out.

    The main thing I want to edit is the front text that goes at the top of the email, ahead of the blog posts that I’ve identified as ones that should go into the newsletter. As near as I can tell, there’s no way to create that text until micro.blog gives me the draft newsletter. By default (the way I had it set up until a few minutes ago), there is then only 30 minutes before the newsletter goes out.

    That might be fine, except in practice it turns out that the alert arrives after I’ve left on my main morning dog walk, and then the newsletter goes out before I get back.

    A dog standing on a picnic table

    As a stop-gap I’ve increased that gap to 3 hours (the largest gap the system allows, it would appear). That’s not perfect—I’d like to be able to write the front-matter anytime in the month before the newsletter goes out, and then edit it repeatedly over the month. But it’s good enough that at least I won’t keep missing it just because my dog gets to luxuriate in a long morning walk every day.

    Another guy said:

    “Maybe the reason the cat’s ok and needs to sleep all day is because it spends all it’s waking time doing parkour. If you did parkour all day and then slept for 12 hours you’d probably be able to keep up with the cat.”

    To which I said:

  • Not really AI (happens every time)

    As someone who’s been paying attention to AI since the 1970s, I’ve noticed the same pattern over and over: People will say, “It takes real intelligence to do X (win at chess, say), so doing that successfully will mean we’ve got AI.” Then someone will do that, and people will look at how it’s done and say, “Well, but it’s just using Y (deep lookup tables and lots of fast board evaluations, say). That’s not really AI.”

    For the first time (somewhat later than I expected), I just heard someone doing the same thing with large language models. “It’s just predicting the next word based on frequencies in its training data. That’s not really AI.”

  • Writing, and plans for writing

    I have written very little in a long time. But today I started working on something new, and I have a plan to get another (related) thing that I wrote a while ago ready to submit.

    The older thing is a bit of steampunk-esque whimsy that I started as an experiment in voice, and found I rather liked. As it grew, I realized that it was longer than a short story, and a market I was interested in was about to open to novella submissions, so I thought I’d just let it grow.

    One thing I do when I’m writing is to just drop bits in that seem cool, as possible set-ups for later bits. This often works out very well. Sometimes, though, those bits of set-up imply stuff that doesn’t get written. That happened this time, and I made a list of bits that either needed the follow-up stuff written, or else be deleted.

    Since I was aiming at novella length (and I wasn’t there yet), I figured that I could just write those bits out. But several didn’t end up working out. So now my plan is to make another pass through the planned novella, delete the bits that didn’t go anywhere, turn it into a novelette, and get it submitted somewhere.

    But that is all work for another day. Today I’ve started on something new: a sequel to that story. I remain delighted by the characters, by the steampunky world, and by the voice I used to write the story. And yesterday I came up with part of a new idea.

    Just now I jotted down a few sentences, which I very much hope to get back to later today.

  • Visited the New England Botanic Garden

    As one of many pleasant outings during our visit, Steven took us to the New England Botanic Garden. It was a good choice for the group, providing opportunities for walks of all different lengths for people who wanted to walk further or less far.

    There were, of course, lots of plants to see (f you’re a fan of diverse hostas, you’d be in heaven), but I found myself drawn to the art, and particularly enjoyed the sculptures. Although not religious myself, I don’t mind religious art, but I do find the endless Christian iconography one tends to find especially in the Midwest to be tedious. So I always enjoy anything different.

    The New England Botanic Garden had a lot of western classical art, one sort I particularly enjoy. (I always like allegorical personifications (like Liberty and Justice, but lots of others as well), and I saw figures for Summer and Autumn (although I failed to get pictures of those). I also like classical western architecture—especially faux architecture, such as follies, which they had one of, along with a Temple of Peace. And I did manage to capture a photo of the statue of Pan.

  • I’ve spent too much time thinking about longevity

    I’ve been thinking about longevity too long and too hard. It isn’t something that I suddenly started doing when I reached my 60s, or even when I hit middle age. I can remember as a high school student figuring out that I’d need to live about two thousand years to have time to learn and do all the stuff I wanted to learn and do.

    Sadly, everything we know now suggests that lifestyle improvements can get you a life extension of 7 years—maybe as much as 11 years, if you get serious about it. I mean, that’s not nothing, but it’s not going to get me to two thousand years, or even to eleventy-one, like Bilbo. (That’s what I lowered my sights to, when I realized that two thousand years was unlikely.)

    I was briefly pretty hopeful in the late 1980s, when it looked like nanotech might produce amazing longevity gains. But, no. Turns out except for a few materials-science things—stuff like that tweaking the surface of glass to make it self-cleaning—the only nanotech that anyone has been able to get to do anything remotely interesting is biotech. I mean, MRNA vaccines are awesome, but nothing like the nanotech we were promised.

    Considering how much is written about longevity, the stuff that actually works offers pretty minimal benefits. Getting a life extension of 7 to 11 years look pretty easy, just by doing the obvious, boring stuff, and practically none of the fancy bio-hacky things have any evidence behind them at all.

    So what are the boring things that work?

    Eat food

    Don’t eat industrially produced food-like substances. Eat in reasonable amounts. Eat diversely. I saw one study that suggested that any exclusion-based diet—keto, carnivore, vegan, etc.—seemed to be associated with poorer health outcomes. (On the other hand, if one of those things produces benefits in the short term—for me, it’s eating low-carb—there’s no reason not to do it long enough to reap those benefits. But long-term you want a diverse diet.)

    Exercise

    Until recently the only real evidence-based exercise advice was for 150 minutes per week of moderate-intensity exercise (brisk walking, basically). But recently it has become very clear that maintaining muscle mass, strength, and power are beneficial in multiple ways (everything from reducing falls to providing a glucose sink). Separately, a high V̇O2 max is strongly associated with a longer life. So although there’s little evidence for weight lifting, running, or high-intensity cardo, there is now very good evidence that the entirely expectable results of those exercise modalities are excellent for longevity. So: diverse exercise is going to help you live longer.

    Manage your blood pressure, blood glucose, and blood lipids

    Really good diet and exercise can maybe eliminate the need for drugs. But taking the drugs if you need them can help a lot.

    Enjoy life

    There’s good evidence of benefit from social connection. There’s good evidence of benefit from time spent in nature. There’s good evidence of benefit from having a positive mental attitude. (All those are suspect, because being sick makes them tougher to do, so you’re selecting out some fraction of the people who are going to die young, which makes the statistics misleading. But there’s not much point in a long life unless you’re going to enjoy it, so why not?)

    Other stuff

    I’ve refrained from mentioning the bio-hacky stuff that I’ve spent way too much time thinking about. Not just the nanotech stuff, but also all the rest: All of the supplements, sleep hacks, drinking more (or less) coffee (or tea or bone broth or mushroom-enhanced beverages), etc.

    It’s not that things like sleep aren’t important. It’s that there’s essentially no evidence that any specific intervention is going to help in a measurable way. In fact, there can’t ever be any such evidence. The experiment can’t be done. And if it were done, the effect wouldn’t be measurable.

    I mean, if you have a diagnosis for a problem—sleep apnea, for example—then treating that problem could very easily be transformational, not just for your longevity, but for your life right now. But giving everyone a CPAP machine would do no good. Furthermore, picking a few random sleep hacks—avoiding caffeine after mid-day, wearing blue-blocker glasses, or tweaking your pre-bedtime routine—isn’t going to make any difference across the population. (Any one of those might help you in particular, and if it does, more power to you. But none of those, even if adopted by 100% of the population, is going to add a year to the average lifespan.)

    If you’re interested in details, you might look at the recent New York Times article “The Key to Longevity Is Boring.” Another option would be to read the Peter Attia book Outlive, or listen to his most recent podcast episode, Longevity 101, either of which does a great job of covering the handful of things that will give you that extra 7 to 11 years of life.

  • Newsletter going active!

    I’m finally sending out my newsletter! An “issue zero” just went out, but starting next month you’ll be getting actual newsletters. My first cut at a title is “Sword fighting, writing, and a dog,” because that’s what I seem to be spending my time on these days. (I’ll try to get more writing stuff in than I have been just lately.)

  • My birthday bearpit

    Last night, in celebration of my birthday the day before, my local HEMA club (Tempered Mettle Historical Fencing) honored me with what’s called a “bearpit”: I faced all comers with rapier or longsword for three passes each.

    I made a video:

  • Getting a more accurate 🏃🏻‍♂️ heart rate from my Google Pixel watch

    All consumer-grade heart rate monitors have issues. Chest straps are pretty good. The optical captures from wrist (Google Pixel watch, etc.) or finger (Oura ring) are quite a bit less accurate.

    I’ve generally just tolerated it—taking the reported data with a grain of salt—but sometimes it would be nice to get good data. Today I did a little experiment with my Google Pixel watch—tightening the strap at the midpoint of my run—and found that it seems to give me pretty good data this way.

    A graph of heart rate data, with a distinct break at the mid-point

    What you see is my warm-up, followed by 1 mile out and then 1 mile back. The HR shown for the “out” phase (averaging maybe 180 bpm) is ridiculous—what it’s capturing is not my HR, but rather my step rate.

    In the second half my HR goes from about 160 to slightly above 170 (gradually rising as I get tired), and that’s probably just about right.

    (The standard formula for estimating your maximum heart rate is 220 minus your age, which would give a max HR of 156 for someone of my age. But that’s clearly wrong for me. I pretty regularly see peak HRs of just over 170 that seem entirely legit. I assume that my genes and my training history just give me a higher max HR than typical. Sadly, it doesn’t make me faster, as you can see from my average pace for this run. I was running literally as fast as I thought I could maintain for 2 miles.)

    Anyway, I think I can recommend tightening up the Pixel watch band as tight as tolerable, for getting the most accurate data.

  • RDL

    In my previous post, I talked about RDL (Romanian dead lift) the exercise. In HEMA practice RDL refers to something else: the writers of three famous glosses of Lichtenauer’s Zettel (a long didactic poem on sword fighting) by Sigmund ain Ringeck, Pseudo-Peter von Danzig, and Jud Lew.

    So far, I’m reading a different gloss of the poem (although I’ll probably get to those as well):

  • Adding single-leg Romanian dead lifts

    I recently bought a new adjustable kettlebell. I got it specifically because the adjustable kettlebell I already had has a rather large gap in weights: It goes from 25 lbs to 35 lbs (11 kg to 16 kg).

    I’d been doing clean and press at 25 lbs. (I do a reverse ladder, where I do 5 left and 5 right, then 4, 3, 2, and 1, then put the weight down. That’s one set.) I started at 4 sets, and over a few weeks worked up to doing 10 sets, at which point I figured it was time go up in weight.

    Sadly, it turned out that I couldn’t make the jump. After a failed attempt, I cut the reverse ladder down to start at 3 (rather than 5), and started at just 3 sets. I managed one workout like that, but when I tried to do another workout, I didn’t even make it as far as I had the first time.

    So, I bought a new, more adjustable kettlebell: the Wildman Athletica competition adjustable kettlebell. It will allow me to make ½ kg jumps, if that what it takes to be able to go up in weight successfully.

    A Wildman Athletica adjust-able weight kettlebell

    It starts at 12 kg, which by happy coincidence is right where I need to be for my clean & press workouts.

    The downside of the Wildman kettlebell is that it isn’t so easy to adjust the weight. Whereas my other adjustable weight kettlebell can be adjusted with a quick click of a dial, the Wildman adjustable kettlebell has to be opened up with a hex wrench, and then have weight plates added (or removed), and then tightened back up again. This is no big deal if you have to do it once or twice a month as you finish one cycle in an exercise program, but is pretty tedious if you have to do it every day or two as you switch between exercises—and 12 kg is rather low for lower-body exercises (for me). My other adjustable bell goes to 40 lb (18 kg) and my fixed-weight bell is 53 lb (24 kg)), and either of those is a much for appropriate weight for, let’s say, kettlebell swings.

    So, I was trying to think of a lower-body exercise I could do with just 12 kg, and still get a reasonable muscle-building stimulus. I thought about hand-to-hand swings, which would work okay for the upper body, but wouldn’t make much difference as far as the lower body goes. Then I thought of single-leg Romanian dead lifts.

    If I were doing regular (2-legged) Romanian dead lifts (RDL) with a barbell, I’d be able to use close to 135 lbs. You might assume half of that would be about right for a single-leg RDL, but the SLRDL turns out to require a much higher level of skill, because it’s a tricky balance exercise, as well as a strength exercise. In particular, it really works the smaller muscles of the feet and ankles—needed to keep from falling over.

    All of which is to say that I think SLRDLs will turn out to be a very fine exercise for my purposes, at least for a while. I started at 5 sets of 5 left / 5 right, and just like with the clean & press expect to be able to run it up to 10 sets. Then, just like with the clean & press, I should be able to go up in weight. At some point—when I get the skill component nailed—I’ll probably see the weight I want for the lower-body exercise go up faster than the the weight for the upper-body exercise. But at least for a little while, I think I’m all set.
