I went to a parkour workshop yesterday held at 25 O’Clock Brewing in Urbana—one small bit of the UnConference (a very Urbana thing).

I’ve been interested in parkour for years now. I have included various bits in my own training, and also gone to train with the campus parkour group (the same people who led this workshop) a few times. For various reasons (social timidity, physical timidity, lack of fitness) I haven’t managed to establish a regular practice of training with the campus group. But it doesn’t mean that I’m not interested, so I was glad to learn about this workshop, which seemed like a safe, easy way to get back into it—and was.

We were led in a warmup, followed by some quadrupedal movement: Bear crawls, aka foot-hand crawls, both frontwards and backwards, followed by a move I know by the name “traveling ape,” although there are probably other names for it.

After the QM we went for a very short run to a wonderful object that could perhaps be described as a free-standing wall of old railroad ties locked in a wire cage. It had a flat metal top which together with the cage made it great for practicing cat hangs: The cage provides enough of a toe hold that even people with limited grip strength can hold on long enough to get a good workout.

The next thing we worked on was shoulder rolls. I was particularly glad for this part because I used to be able to do shoulder rolls, but at some point in the last 35 years lost the mix. Starting from a kneeling position, though, I was able to recover my roll. In just 15 minutes of practice I was back up to doing rolls from a squat. From there I’m sure I can work up to rolls from a standing position pretty quickly.

(Actually, the main delay is that for some reason the rolls made me queasy. I don’t remember that from 35 years ago, but yesterday I got queasy after a few minutes rolling, and my stomach didn’t completely settle down for several hours.)

After rolls we did some vaults. We started with the safety vault, which I’d already learned (and have continued to practice, because it’s really handy for things like getting across downed trees while out hiking). Then we proceeded to some initial progressions for the kong vault. I’d always thought of the kong as the most advanced vault, but that’s when it’s used to traverse a gap beyond the thing you’re vaulting. It can also be used like the safety vault as a way to get on top of some object, and that’s what we learned yesterday. With a low-enough wall (waist-high, rather than chest-high), I can already get on top with a kong vault.

Shout-out to restorative exercise specialist Ashley Price who spotted that the parkour workshop was going on and suggested that I attend.

Today I’ve already included a bit of parkour in the day’s activities, adding a bit of QM to my afternoon walk, both foot-hand crawling and a bit of ground kong. (The latter is excellent practice for reminding myself that I need to keep my knees together, something that does not come naturally.)

HRV (Heart Rate Variability) is one of the metrics that the Oura ring tracks. I’ve begun to learn a bit about it, and thought I’d share what I’ve learned so far, and then share a small personal observation.

Very briefly, HRV has to do with the variations in the timings between heart beats. If your heart rate is 60 beats per minute then about one second will pass from one heart beat to the next—but only about one second. In actual fact, sometimes it will be a few milliseconds more, and other times it will be a few milliseconds less. Those “more or less” amounts are your heart rate variability or HRV.

Most of what I know about the HRV comes from an interview on Human OS Radio podcast with Phyllis Stein, Director of the Heart Rate Variability Laboratory at the Washington University School of Medicine in St. Louis, called Introduction to Heart Rate Variability (HRV). It’s definitely worth a listen, if you do the podcast thing.

A lot of HRV is related to respiration. I noticed this when I got my first heart rate monitor thirty years ago: Every time I inhaled my heart rate speeded up, and every time I exhaled my heart rate slowed down. This effect is pronounced enough that the Oura ring can calculate your respiration rate just by watching your heart rate speed up and slow down with each breath.

HRV is widely used as an indicator of the balance between your parasympathetic and sympathetic nervous systems: If your parasympathetic nervous system is functioning well you’ll see quite a bit of variation. When it’s not functioning well—for example, when you’re persistently stressed—the amount of variation in your heart rate will decline.

Since I got my Oura ring, I’ve been tracking my HRV, looking to see if this or that bit of self-care practice will increase it, and I’ve noticed one thing that seems kind of interesting: Very often my HRV will be quite low in the first half of the night, and then be higher (and with higher variability in the variations) in the second half of the night. Here are three recent examples:

I speculate that this is related to the fact that I’m still digesting supper at bedtime, or perhaps that alcohol I’ve consumed is not fully metabolized yet. I’ve been hoping that life would produce a natural experiment to test those two theories, but so far haven’t gotten one. (That is, days when supper or cocktail hour were very early or had to be skipped have also been days when some other factor—such as illness, an unusual bedtime, or unusual stress—confounded things such that I couldn’t really draw any conclusion about the effect on my HRV.)

At least since David Allen’s Getting Things Done it’s been widely advised that to-do lists be specific to “context”: You have a list of things to do at the office, a list of things to do when you’re at the phone, a list of things to do when you’re in the car, etc.

In the fascinating article Productivity for Precious Snowflakes, Tiago Forte suggests that these sorts of context are much less important than one’s internal context.

Trying to make this work with a to-do list is crazy:

It is not at all clear what must be done and in what order; in fact, it becomes ever more clear that most of the tasks we execute don’t make much of a difference, while a tiny percentage randomly and dramatically influence the course of our work and our lives. It makes sense to invest more and more resources in making that distinction, because the absolute fastest way to complete a task or reach an objective is to realize you don’t have to.

The article goes on at some length with tips for figuring out what state of mind is best for what tasks. And more to the point, figuring out what tasks are best suited to be completed given your current state of mind. And, even more to the point, how to break up your larger tasks into pieces that can be effectively worked on by you in different states of mind as you happen to find yourself in them. There’s also some suggestions on how to learn to enter states of mind that you’ve found to be useful.

Not a new article, but an interesting one.

First, let me say that maximizing my Oura ring activity score is, in and of itself, of no value whatsoever—except to the extent that it reflects and reinforces my efforts to get an appropriate level of physical activity.

Happily, I find that getting an appropriate amount of activity generally results in a higher score. So it works at that level, with perhaps a few mismatches between what I think is appropriate and what the Oura software thinks is appropriate, the main one being their idea of what counts as a recovery day.

Periodization of training—getting a mix of training days and recovery days—is a great idea. In fact, the lack of periodization is one of the limitations with Google Fit, whose model is to have a daily activity goal which is a little aggressive—a goal that motivates you to to get out and walk just a little more than you otherwise might. The problem is that a goal that’s even a little bit aggressive is going to be excessive for your recovery days, while still being much less than you probably want for your training days.

This is where the Oura ring software is a big step up from Google Fit. It strongly encourages both training days and recovery days. Unfortunately, its idea of a recovery day seems a bit too strict for me:

For Oura, an easy day means keeping the amount of medium intensity level activity below 200 MET minutes (200-300 kcal/day), and high intensity activity below 100 MET minutes (100-150 kcal/day).

In practice this can mean doing lots of low intensity activities, getting healthy amounts of medium intensity activity (30-60 min), but only a small amount of high intensity activity (below 10 min).

Now, that’s all well and good, except that ordinary walking is a medium intensity activity, and (except when the weather is crappy) it’s a very rare day indeed that I don’t end up walking more than an hour—meaning that I basically never get a recovery day in Oura ring terms.

The result is that whenever the weather is nice my activity score starts dropping, because I’m not getting what my ring thinks is appropriate recovery. Then, when there’s a couple of days of crappy weather and I sit around the house all day, my score will climb (as my recovery time value improves). Then, as soon as the weather gets nice again and I can get out and be active, my activity score can shoot up into the high 90s:

However, I can only get five days of such high levels. Since I need to have at least two recovery days per week, a string of more than five nice days means my recovery suffers once again, turning into lower activity scores.

I haven’t fully characterized the behavior so far, but it seems like the software may well be doing just what the quoted text above says: Getting between 30 and 60 minutes of medium activity makes a day a recovery day, with a hard end to any “recovery” at 61 minutes.

If true, that would probably be the place to make a fix. That is, I’m not trying to suggest that I have any data to show that an average person could walk more than 60 minutes and still recover as well, nor do I have any good metric for identifying some subset of people who can walk more and recover well. But I am pretty sure that the 1 h 3 min of medium activity that I got the day before yesterday is not so much more than the 60 I got yesterday that the former should count as a training day rather than a recovery day.

Does money come with new-agey energy flows or emotions attached? For most of my life, I’d have said no (or more likely just rolled my eyes at the question). As you might expect from an economics major, I bought into a free-market model of how money worked.

Experiences over the course of my career, gradually convinced me that those ideas were . . . Well, not wrong exactly, but incomplete. I came to understand that money isn’t the kind of neutral object that it is in economic theory.

Ken Honda’s new book will let you skip over the 25 years of first-hand experience it took me to figure this out.

If you think money is a neutral, transactional artifact, then it just makes sense to earn as much as you can in the easiest ways possible. Because I was a software engineer whose career started in the early 1980s, it was pretty easy to find a job that paid well, and salaries grew rapidly, so I was doing just fine as an employee. There are certain things that come along with being an employee, the main one being that you’re supposed to do what your boss tells you to do.

I was okay with that. More okay than a lot of my coworkers, who objected when the boss wanted them to do something stupid or pointless.

My own attitude was always, “Yes, attending this pointless training class is a waste of time that I could be spending making our products better. But it’s easier than doing my regular work, and if my boss is willing to pay me a software engineer’s salary to do something easier than write software, I’m fine with that.”

The idea that I was fine with that turned out to be wrong. In fact, putting time and effort into doing the wrong thing is a soul-destroying activity. Getting paid a bunch of money for it doesn’t help. That money is, in Ken Honda’s terms, Unhappy Money.

Money that flows into (or out of) your life in a positive way is Happy Money—money that you receive (or give) as a gift, money that you earn by doing something useful (or spend to get something that you want or need). Unhappy Money is money lost or gained by theft or deceit, paid grudgingly by someone who feels cheated or taken advantage of—or, as in my own case, paid willingly, but paid to someone who doesn’t think what he’s doing to earn it is worth doing.

Honda’s thesis is that if you adjust your life around this idea—so that your own money flows are all Happy Money (and that you refrain from receiving or spending Unhappy Money)—your life will improve. My experience is that this is true.

If that insight is the key to the book, probably next most important is understanding that “There’s no peace to be found in always wanting more,” which is one of the points I tried to make when I was writing for Wise Bread.

To be honest, probably one reason I like the book so much is that a lot of the practical advice sounds a lot like what I talked about for years at Wise Bread. (For example that the strategy of just saving more quickly reaches limits in terms of its utility for making your family more secure.)

Much of the book is on the details of how to shift all aspects of your financial life toward Happy Money. There’s a long discourse on what he calls your “money blueprint”: The attitudes and practices passed down from parent to child (or rejections of those attitudes and practices), people’s basic personalities, and simple ignorance about how money works. A crappy money blueprint will predictably lead to people into cycles of Unhappy Money flows.

I’ve been interested in money for a long time, at least since sixth grade. Between studying economics in college, and embarking on an enduring interest in investing, I’m sure I’ve read hundreds of books on money. Among them, Happy Money: The Japanese Art of Making Peace with Your Money stands out.
