Deadly actinic rays

I shared a link to this article by Rowan Jacobsen, with the comment “This article falls so squarely in the sweet spot of reinforcing my own preconceptions, I almost hesitate to tweet it.” But I did, with a few brief quotes.

Freed of the limitations of twitter, here’s a more extended excerpt:

Lindqvist tracked the sunbathing habits of nearly 30,000 women in Sweden over 20 years. Originally, he was studying blood clots, which he found occurred less frequently in women who spent more time in the sun—and less frequently during the summer. Lindqvist looked at diabetes next. Sure enough, the sun worshippers had much lower rates. Melanoma? True, the sun worshippers had a higher incidence of it—but they were eight times less likely to die from it.

So Lindqvist decided to look at overall mortality rates, and the results were shocking. Over the 20 years of the study, sun avoiders were twice as likely to die as sun worshippers.

There are not many daily lifestyle choices that double your risk of dying. In a 2016 study published in the Journal of Internal Medicine, Lindqvist’s team put it in perspective: “Avoidance of sun exposure is a risk factor of a similar magnitude as smoking, in terms of life expectancy.”

Jacobsen later mentions the app dminder, which I’ve been using for several years now. It helps you optimize your sun exposure (getting maximum vitamin D production without getting sunburned, based on time of year, time of day, location, and skin pigmentation). I just checked the app, which tells me that it’s just 8 days until the vitamin D window reopens here in Savoy, Illinois!

I concluded my little tweet storm with this: Pretty much every nice day of the spring, summer, and fall, I announce to my wife around midday that “I’m going out to expose my integument to the deadly actinic rays of the sun.” And then I do. I feel so much better since I started doing this.

Movement in 2018

This year’s review of my movement practice will be a bit less detail-oriented than last year’s, when I included a long list of exercises, and a long list of non-exercise movement that I’d engaged in over the year. This year I exercised a bit less and moved a bit more, and came to a balance that I’m pretty happy with—that I don’t feel much urge to analyze.

I continued the winter exercise regimen that I described a year ago for the rest of the winter, but then let most of it go in favor of less-structured movement. As I say, I’m pretty happy with what I ended up doing, although the result was a decline in some of the strength increases I’d made.

Summer included a lot of solo walking (mostly in natural areas very close to home) and a lot of walking with Jackie (in a wide range of environments, including natural areas somewhat further afield).

One major piece of our walking was our big trip to Utah, where we got in plenty of hikes in Bryce Canyon, Zion Canyon, and Arches. (See image at top.) The length of any particular hike was nothing to write home about (although we did write home a bit), but the ruggedness—and especially the steepness—made the hikes very different from anything we manage at home.

Basically, summer was great—lots of time spent in the sun, lots of walking, lots of time spent with my sweetie, lots of time spent alone.

As summer transitioned to fall, I had the same problems I usually do, perhaps slightly worse this year than average because the transition seemed more abrupt, with early fall being unusually cold. Happily, late fall was no worse than early fall, and what was unusually cold for early fall is actually rather mild for early winter.

One thing I have done this fall is get back to running. In the past I’ve always meant to establish a running habit that I can carry forward into the cold months, and I have nearly always failed. This year, so far, I’m doing okay, getting in a couple of runs a week, with long runs of 5 miles or more. With just a little luck (not too icy, not too much bitter cold) I’ll be able to carry a lot more aerobic fitness into the spring than I usually manage. That would make it possible to do a spring running event, if I want.

I’ve had very good luck this year on the injury front, managing to stay healthy though the whole year.

I still teach taiji, both the beginners class and a class for continuing students, and it remains rewarding it all the ways it has been—physically (I get my own taiji in), mentally/emotionally (I get my meditation in), socially (I gather with a group of friends several times a week), and financially (admittedly in a small way).

Looking ahead, I’m rather inclined to stick with a movement focus, spending more time doing stuff (moving) and less time preparing to do stuff (exercising).

Weird (horrifying) study of human movement

A couple of weeks ago the New York Times linked to a new study on age-related declines in human movement. It’s an odd study, but not because of the result (which shows that children start moving less at age 6), because that seems entirely predictable to me, despite the general understanding previously having been that the decline started in adolescence.

Rather, what makes the study seem odd to me is the weird blind spot the researchers seem to have about when and how organisms (including humans) choose to move.

In the study itself the researchers make clear that they had considered the obvious presumption—that kids start moving less when they start going to school: “The overt explanation for this earlier decline could be the increased sitting times due to school.”

The blind spot I’m talking about is presented in the next sentence, where they immediately qualified that:

However, time-specific analysis of [physical activity] has revealed that in addition to the increased [sedentary behavior] during school hours, there was also a distinct decline on weekends, out-of-school days, and during lunchtime.
Schwarzfischer P, Gruszfeld D, Stolarczyk A, et al. Physical Activity and Sedentary Behavior From 6 to 11 Years.Pediatrics. 2019;143(1):e20180994

What’s weird and horrifying is that they make that statement seemingly without it occurring to them that forcing children to sit still for hours on 5/7ths of the days of the week might affect their behavior on the other 2/7ths of the days.

Right off the top of my head I can think of four obvious reasons that would be true:

The required behavior in school normalizes the behavior of extended sitting.
Even a few weeks of enforced extended sitting will result in the kids becoming deconditioned aerobically, making physical activity more difficult and less appealing.
Extended periods spent in any static posture—especially the static posture of sitting—will begin the process of reducing their range of motion (they’ll pretty quickly lose the ability to squat, for example), again making physical activity more difficult and less appealing.
The addition of “physical education” to the kids daily schedule sets the pattern of replacing movement with exercise—a time-bound, regimented activity which attempts to pack the health benefits of a week’s worth of movement into just a few hours. (I’ve written about this before.)

Just one instance of this blind spot is bad enough, but it shows up again in in a key reference. The researchers say that it is accepted that physical activity declines with age: “A natural and biologically determined decline of total [physical activity] throughout the life span seems likely.” They support that assertion with a couple of references, one of which looks specifically at movement in non-human animals.

Unfortunately that study (Ingram, D. K. Age-related decline in physical activity: generalization to nonhumans. Med. Sci. Sports Exerc., Vol. 32, No. 9, pp. 1623-1629, 2000, which is sadly behind a pay-wall.) has exactly the same blind spot: All the animals studied were captive animals. That study looked at how animal movement varies when an animal is moved from its “home cage” to some other cage. I can’t say I’m the least bit surprised the behavior of those captive animals closely resembles the behavior of children moved from home to school and back again.

I would be very interested in studies that included some free-range animals. (Which isn’t something I can do, but which seems at least possible now that accelerometers are cheap.)

Of course school isn’t the only factor that inhibits children from moving more. The restrictions on self-directed play so well documented by Lenore Skenazy of Let Grow no doubt feed in as well.

So it would be great if there were studies of movement in free-range kids as well.

The final weird and horrifying thing isn’t anything new, but is something I hadn’t really been aware of before: The assumption that an age-related reduction in movement is “natural and biologically determined,” has led directly to public policies that normalize it:

This decline is also represented in recommendations from the World Health Organization (WHO): preschool-aged children should accumulate a minimum of 180 minutes per day of total [physical activity], children and adolescents (4–17 years old) at least 60 minutes per day, and adults only a minimum of 30 minutes per day in moderate-to-vigorous physical activity (MVPA).

To which I say, “Argh!”

I probably wouldn’t be so struck by this if I weren’t already tracking my own movement. (Cheap accelerometers again.)

For some time now I’ve been working to a goal of 105 minutes of movement per day, and over the last few weeks I’ve come pretty close, averaging just over 102 minutes of movement per day, according to Google Fit. (This number, based primarily on steps, somewhat underestimates my movement. In particular it gives me almost no credit for the time I spend teaching taiji, because although there’s plenty of movement, there’s not much stepping.)

The WHO recommendations make me strongly motivated to upgrade my goal for movement to 180 minutes per day.

Why should kids under 6 get all the fun?

Oura-ringing out the old year

For a couple of years now, I’ve been having some trouble sleeping. It’s not a constant problem, but it has become more frequent than the rare thing it used to be.

I think the problem is just a string of one-off instances of stress. During this period I had one older relative begin having cognitive difficulties and have to move to a facility that could provide additional care, my cat got sick and eventually died, had some personality clashes related to volunteer work I’m doing grow into a problem that eventually involved lawyers, and had another older relative began showing signs of cognitive difficulties.

Each of these resulted in a pattern where I’d fall asleep just fine, but then wake up in the middle of the night and start ruminating about the issue of the day and be unable to fall back to sleep for an hour or three.

In the past when I had problems of this sort they tended to be short-lived. I’d stress out about something for a night or two or three, but the issue would be resolved soon enough and I go back to sleeping fine.

Here the issues have stacked up, new ones following the old ones. Further, some of them don’t go away. They linger on.

As I say, I think that’s what’s happening here. Ordinary life stresses have simply come at me a little too hard and a little too fast, with the result that my sleep has been impacted.

However, maybe that’s not all that’s going on. Maybe there’s more to it. I know there are some other issues. For example, if I don’t keep my carb intake down my nasal congestion returns, and that dramatically interferes with my sleep.

Given that I’m not sure what all might be wrong, I thought it might make sense to investigate further—gather some data, and see if I couldn’t find some patterns in my sleep problems. To that end, I bought an Oura ring, a tracking device along the lines of an Apple watch or a Fitbit, but with its focus specifically on gathering and analyzing data about sleep.

I’ve only had it for a week so far, and I’m really just getting started at looking for trends in the data. For example, three nights ago I slept poorly (awake for almost 2.5 hours of the almost 9 hours I was in bed).

One possible reason was a too-large meal too late in the day. (It was the Winfield Village holiday party.) One piece of data that suggests that possibility is that my body temperature was elevated by 0.3℃ during the night—perhaps because of increased metabolic activity digesting all that food.

Interestingly, I got more deep sleep than I had all week up to now, perhaps because I went for a long run the day before. (Deep sleep is where you get the physical recovery from things like heavy weight-lifting sessions and long runs. Maybe the first few nights had less deep sleep simply because I didn’t need more than that, because I hadn’t had the hard workouts that require deep sleep for recovery.)

Here’s the next night, where I spent less time awake and almost as much time in deep sleep:

My body temperature was still up, though, even without the big meal. We had turned the thermostat down one more degree, but that’s about as low as we want it, so last night I rearranged the covers, removing the down comforter, going with just the wool blanket. I don’t know if that was a key change, but I slept very well last night:

Not only were my quantities of total sleep and deep sleep good, some of the other metrics were good as well. My temperature deviation was -0.3℃, which suggests that maybe I’ve got the covers and thermostat thing balanced just about right. My resting heart rate was down to 47, which suggests that I’ve recovered completely from the long run I took three days ago.

My hope is that by paying attention to this sort of thing, I can gradually eliminate these sorts of problems affecting my sleep. Of course that will leave me with the stress-related problems, but I think I know how to handle those—fixing the ones that can be fixed, accepting the ones that can’t be fixed, and engaging in appropriate self-care to help myself handle the stress better. And, of course, get enough sleep.

Winter running, maybe

I have never been a winter runner. Most years I start running in the spring, ramp up the length of my long runs during the summer, make a plan to keep running through the fall, and then abandon it at the first sign of cold.

I’d like to run over the winter. Exercise helps as much as anything else I’ve tried to stave off SAD. Besides that, there are any number of spring running events that I’d enjoy participating in that I can never do because I’m not in shape until later in the year.

And so, demonstrating my unwillingness to learn from experience, I’m trying yet again to run over the winter.

To help get myself started, I’ve embarked on a consumer binge. First I bought a high-viz hat. (I already had the high-viz running vest and the red buff with reflecty stripes.)

The hat got me out for a run or two.

Another garment that I didn’t really have was running tights. Having a pair of running tights, I figured, would eliminate one more excuse for skipping a run in the cold. Plus I was able to find a pair marked down from $80 to $20.

I wore the tights for a 5-mile Thanksgiving Day run. (See map at top.) That’s my longest run in a couple of years, and I felt great right along—no sore ankles, and no sore knees (the places that tend to hurt when I push the distance up too fast).

I did wake up this morning with sore feet—classic plantar fasciitis pain. My feet only hurt for a few minutes in the morning, which is typical with minor plantar fasciitis. I expect it will resolve itself in just a day or two, but even if it does, it’s a pretty strong indication that 5 miles is as far as I should run for a while. (I’d had no foot pain after my previous long run of 4 miles.)

To give my sore feet a break I didn’t run today, opting instead for a 3.2-mile hike at Homer Lake. The trails there are pretty flat and level, but there are some places with lots of tree roots right at the surface, which make for a nice complex surface to walk over, giving one a chance to mobilize the foot joints, highly beneficial for preventing plantar fasciitis.

I’ll post further winter running updates, if I manage to get the habit established this year.

Ignorance about retiring early

It’s been eleven years since I retired, at age forty-eight.

I hesitated at first to call it “retiring early,” even though in my head that’s exactly what I was doing. Partially that was because I hadn’t decided to take the plunge. I had been intending to retire early, doing the planning, doing the saving. But part of a proper early retirement is deciding that you’re ready, based on having established an income stream that covers your expenses.

I hadn’t done that. What I did was learn that my employer was closing down the site where I worked, and then wing it. I counted my money; I did some figuring. I secretly figured that I could retire, but I didn’t tell people that. What I told people was that, “Although I couldn’t retire, I had reached the point where I didn’t need to work a regular job any more.”

I’d meant to celebrate the 10-year anniversary with a post about how things had gone, but haven’t gotten around to it. And I guess this isn’t going to be that post either, because I’ve gotten so annoyed by an ignorant article by Jared Dillian in Bloomberg Opinion, The ‘Radical Saving’ Trend Is Based on Fantasy—which manages to both be wrong about the facts, and (more fundamentally) miss the whole point—that I’m compelled to write a response.

Dillian’s item number one manages to be both wrong on the facts and miss the point in roughly equal measure:

Most people save now because they want to consume later. But the FIRE folks don’t want people to consume. For the FIRE folks, the point of saving is simply not to have to work. To give you the freedom to do whatever you desire over the last 50 years of your life. Trouble is, the freedom to do anything you want isn’t much fun when you’re hemmed in by a microscopic budget.

First of all, the “financial independence/retire early” (FIRE) folks do want to consume. It’s just that they’ve figured out that, at some point, just consuming more doesn’t make your life better. Rather, they’ve thought deeply about what they need to consume to make themselves happy, they consume that, and then they stop consuming.

I think of it as drawing a line under the stuff that’s worth paying up to get all I want of exactly what I want, and then paying zero for the things that don’t make the cut. (Most people don’t do this. Instead of a cutoff they have a gradual trickle off, spending smaller and smaller amounts as they work their way down the list of things they want. This is no way to be happy. The money they’re spending on stuff they only kinda want eats into the money they could be spending on the stuff they really, really want.)

Second, the whole point of FIRE is not to “simply not have to work.” Rather, the point is to free yourself to do whatever work you want, instead of whatever work pays best. Everybody I know who’s retired early still works at something.

This point is made very clearly by literally everybody I know of who has written about FIRE. To miss it suggests either that Jared Dillian was very careless indeed in doing his research, or that he is willfully missing the point.

Third, it’s simply false to say that “the freedom to do anything you want isn’t much fun when you’re hemmed in by a microscopic budget.” Rather, the freedom to do anything you want enables you to do the most important thing you can think of.

Maybe the most important thing you can think of is really expensive (in which case you’d have saved a lot of money to fund your retirement). But very likely the most important thing you can think of is free, or cheap, or even modestly remunerative. (The list is endless—crafting musical instruments, researching obscure topics in your field you didn’t have time for while working full time, helping care for a family member, documenting the history of your ethnic group, researching the natural history of your region, working for a candidate or a political party or a non-profit that’s trying to stop global warming or child trafficking or hunger or poverty…)

Finally, who says your budget has to be microscopic? Rather, your budget should fund your planned expenses. If the most important thing you can think of is to take a round-the-world cruise every year, you’ll want to save more money than someone whose most important work is to study the local mosses.

I’m going to skip over his second item, because he just makes the same mistake again, imagining a purpose of being able to “consume more later” is a better justification for saving than being able to live exactly the life you want to live and do your most important work.

His third item manages both to make the same mistake yet again, and to insult everybody who understands the difference between the most important work you could do and the work that pays the most:

What is wrong with working? Why do the FIRE people dislike working so much that they want to quit at age 35? Working gives people purpose… I have had unpleasant jobs, and even working an unpleasant job is preferable to not working at all. I am one of these people who thinks there is dignity in working, that every job is important no matter how small.

(I left out a random swipe against basic income.)

I don’t know any FIRE people who dislike working. I know a lot of FIRE people who dislike working at regular jobs. I know a lot of FIRE people who dislike working for psycho bosses, bosses who take inappropriate advantage of them, and stupid bosses who don’t know how to do their job well. I know a lot of FIRE people who think there is great dignity in choosing to do whatever they think their most important work is, regardless of whether it pays enough to live on.

I’ve worked at bad jobs now and then. Not unpleasant jobs, which are okay as long as the work is worth doing. But some jobs are not worth doing.

One example: a manager one place I used to work put huge pressure on employees to finish a task, despite knowing that the project the task was for had been canceled —because completing the project on-time was required for the manager to get a big bonus. That is work that was not worth doing. (Literally. It produced nothing of value to the company, while keeping the employees from doing something that would be valuable.) That sort of situation, which is more common that you might think, is what FIRE people are trying to escape.

Finally, Dillian suggests:

The biggest issue with the FIRE movement is that it’s the ultimate bull market phenomenon. FIRE seems to work because the stock market has gone straight up. A bear market will change that. Even if stocks do return 8 percent to 12 percent over time, it’s not going to be any fun living on a shoestring budget and watching your nest egg decline in value by 30 percent to 50 percent.

Here I have actual first-hand experience. My early retirement started in the summer of 2007, and pretty much right after that came the financial crisis in which my stock portfolio lost about 40% of its value.

I engaged in some pretty dark humor during those first two years, joking about how I wouldn’t want to be retiring early in that kind of market.

In fact, I was just fine. I did the obvious things: I found a way to earn a little money (in my case by writing, which was what I wanted to do anyway), and I got a little extra frugal (on a temporary basis, to preserve my capital).

So, yes, I did live on a “shoestring budget” for a few years while watching my nest egg decline—although not by as much as 30%, even though the stock portion lost 40%, because the bond portion soared and the cash portion remained stable (although the income it produced declined).

Contrary to Dillian’s concerns, it was actually great fun. I was writing full time—fiction in the mornings and articles about personal finance and frugality for Wise Bread in the afternoons—which was exactly what I wanted to do. We didn’t travel much, and we didn’t buy much in the way of new clothes, but we were very happy.

Since then my portfolio has more than recovered. Part of that was just the bull market. Part of it was basic portfolio re-balancing, which automatically had me sell bonds near the peak and buy stocks near the bottom.

After all, the 4% rule (which I assume is what Dillian is implicitly rejecting) was never a law of nature. It’s always been just an empirical guideline. The FIRE people all understand that you can’t just “set and forget” your spending. Instead you need to pay attention, and adjust as needed. Maybe you need to spend less. Maybe you need to find a way to earn a little money. I did both those things, although not very much of either one.

For eleven years now I’ve spent every day doing exactly what I chose to do.

What I chose to do has varied, of course. At first it was all writing. When I realized that I wasn’t taking full advantage of not needing to be at my desk during working hours, I rearranged my schedule so I could spend more of the daylight hours engaged in outdoor exercise. I took a taiji class, discovered that I really enjoyed the practice, and persisted with it. Now I teach taiji, and it has become one of those modestly remunerative things I was talking about.

But for eleven years, it’s always been whatever I most wanted to do.

Minimally processed food

Eating low-carb has been a useful tactic for me—when I watch my carbs, my allergy symptoms are greatly eased—but that doesn’t change the more fundamental truth of Michael Pollan’s basic rules: Eat food. Not too much. Mostly plants.

That first rule is the most important, and would be very nearly enough all by itself, if followed strictly. Probably the way in which “low-carb” helps me as a tactic is that it eliminates whole categories of “foods” which fall short of being food, but which were in my diet for so long, and which I enjoy so much, that I’m otherwise inclined to eat them anyway.

By “food,” I’m referring to industrially produced food-like substances. And, of course, it’s not so simple as that. Twinkies and Doritos are out at the far end of the “ultra-processed” spectrum, but what about the near end? I used to eat a lot of children’s breakfast cereals—which with all the fiber removed and large amounts of sugar added are clearly ultra-processed. But what about more grown up breakfast cereals—processed, but made from whole grains, maybe with a bit of fruit or nuts added? What about granola?

Really it’s just about impossible to eat food without processing. A green salad is pretty minimally processed, but I like my lettuce picked, washed, cut or shredded into bite-sized pieces, and drizzled with a bit of olive oil and vinegar (each of those latter two somewhat processed in its own right). Maybe if you get down on the ground and chomp down on a live lettuce plant you could say you were eating unprocessed food.

I started thinking about this when I saw a pair of lists—processed foods and unprocessed foods—in “Nutrition Action,” a publication which aims to be evidence-based, but which has some striking idées fixes, particularly as relates to low-fat, as illustrated in these lists: generally unremarkable, except that they bizarrely included 2% milk as an “unprocessed” food.

Now, raw milk from a single cow is arguably unprocessed. Mix it with the milk of another hundred cows, pasteurize it, and homogenize it and I think it’s already a bit of a stretch to call it just minimally processed. But to then remove half the milk fat and call that “unprocessed” to me is a bridge too far.

With ragweed season in full swing, my allergy symptoms have clicked into high gear. I’ve belatedly gotten back on very low-carb diet and am already (after just one day) feeling much better.

This time I’m trying to keep more of an “eat food” perspective on the whole thing. I don’t want to fear fruits, just because they’ve got carbs. (I am staying away from fruit juice, at least until I’m sure I’ve got the inflammation fully back under control.) I’m being even more cautious of grains, but not hesitating to include a little rice. I haven’t eaten any lentils yet, but I won’t hesitate to include them either.

I don’t want to say it’s not the carbs, because it is. But with a very few exceptions (like honey and potatoes) it’s only with ultra processing that it becomes at all appealing to eat excess carbs. If I eat food, I’m not going to have to worry about the carbs.

Here’s a photo of Jackie minimally processing some okra for the gumbo pictured at the top of this post

Exercising in the heat

I have always enjoyed exercising in the heat. In this I seem to be different from most people.

I originally took note of this fondness back in the early 1980s when I was living in Ft. Lauderdale. A ritzy local tennis club—way too expensive for me—offered summer memberships for just $100. I just got access to the outdoor courts and not to the indoor amenities, but all I wanted was a place where I could reserve a court and know that it would be available when I met someone there. The only downside was that you were playing tennis outdoors, in the summer, in Ft. Lauderdale. And it turned out I was okay with that.

I’m pretty careful not to be stupid about it. (And successfully so, it seems—I’ve never gotten heat exhaustion or heat stroke.) If I start feeling tired, thirsty, or overheated, I slow down, move to the shade, and drink some cold water.

Over the years I’ve had a variety of theories about why I didn’t mind exercising in the heat when other people hate it so much. I like to imagine that I’m just better at tolerating the heat than the average person: Everyone slows down in the heat, but maybe I slow down slightly less; at some high temperature, maybe I’d become competitive! More likely, since I’m not competitive I’m not making unfavorable comparisons between my speed in the heat versus my speed in cool weather, so the fact that I slow down doesn’t make me unhappy.

Recent research has given me a new, much more likely reason why I like exercising in the heat. On Rhonda Patrick’s Found My Fitness podcast, I heard an interview with Dr. Charles Raison, in which he described the results of a study suggesting that Whole-Body Hyperthermia was an effective treatment for depression. The experiment used infrared lights to heat people up to a core body temperature of 38.5℃ (101.3℉), but Raison is convinced that there is nothing special about the device used, and that a sauna, hot spring, sweat lodge, hot yoga—or just exercising in the heat—would have the same antidepressant effect.

Dr. Raison is studying further to try to elucidate the mechanism by which hyperthermia boosts mood in depressed people. (It seems to reduce inflammation, perhaps by boosting IL-6 which activates IL-10. Heat Shock Proteins might also be involved, since they do all sorts of things.)

I have always been inclined to blame a lack of daylight for the seasonal depression that I’m prone to suffer from during the winter—both too short of a photo-period (which I address with a HappyLight™) and too little vitamin D (which I address with vitamin D supplements), but it now occurs to me that a lack of opportunity to exercise in the heat (and thereby raise my core body temperature high enough to trigger whatever it is that reduces depression) may be an independent factor.

It seems very likely that, just like my desire to spend time outdoors in daylight is probably self-medicating to boost my vitamin D and regulate my circadian rhythm, my desire to exercise in the heat is probably self-medicating to boost my mood.

I hesitate to rejoin a fitness center just to get access to a sauna, but I’ll have to investigate options for access to winter whole-body hyperthermia.

Vitamin texture

On my Flickr feed I shared several pictures of the rocky canyon paths that Jackie and I hiked in Utah with the tag “vitamin texture.” Katy Bowman uses the term to talk about how always walking on flat, level paths fails to provide some of the “movement nutrients” our feet, ankles, calves, knees, and other body parts need to be healthy and capable.

There’s not much in the way of rocky terrain here in Central Illinois (although there are some forest paths with enough exposed roots to produce a reasonable degree of ruggedness). There’s also not much in the way of ordinary hills unless you’re willing to drive for at least half an hour, but I do have one reasonably convenient hill: the highest point in the county is just a couple of miles away—a man-made hill in Colbert Park.

Jackie and I walked there a couple of days ago and climbed up and down the hill a couple of times. The image above is the view from the top of the hill, and here’s an image of Jackie walking up:

It’s not like the climbs in the canyons:

But it’s steep enough to provide a good calf stretch.

I’ve thought to use the Colbert Park hill for running hill repeats, but it’s just far enough that I’m generally not up for running there, running hill repeats, and then running home. (I think I did that one time, about two years ago.) I could drive to the park, but that just seems too lame. Still, my running is coming along okay this spring, so maybe I’ll be in shape to do hill repeats in the middle of a five-mile run pretty soon.

Achievement unlocked: One-arm hang

In the Runner’s Rehab class I’ve been taking, which is mostly lower-body alignment, mobility, and strength, Ashley usually includes a few minutes of upper-body work as a bit of a break. We’ve done hanging from the high bar, playing with parallel bars, playing on a climbing rope, etc.

One time when we were hanging, Ashley asked if I could hang from one arm, and I said, “I don’t know. I haven’t tried in a long time. I can sort-of brachiate on the monkey bars, so I guess I can hang for at least a moment….”

So I figured I’d try, and: Wow! I can hang from one hand!

I haven’t done it for time yet. When I hang from one hand my body turns out. I haven’t yet gotten that under control enough to hang for very long without feeling like I’m going to twist my shoulder.

Still, it give me a feeling of considerable satisfaction to be able to hang from one hand, even if just for a few seconds.

I don’t think this twisting is really a strength issue; more a motor-control/patterning issue. It shouldn’t take me long to get to the point where I can control the twist, at which point I’ll be able to hang for as long as my hands are up to it, and I think they’ll be up to a reasonable amount of one-arm hanging pretty quickly.
