IndieBookClub

I’ve been an avid reader since I was a little kid, but very much not a tracker of things I read. In 6th grade I could have gotten some little prizes for reading a lot, if I’d been willing to go to the trouble of documenting the things I read, but I seriously could not be bothered to do so.

Very occasionally though, I miss having a record of things I’ve read, such as when somebody asks me, “Read any good books lately?”

I never signed up for Goodreads, and was glad I had not when they got bought. (Letting large corporations use my data to improve their bottom line bugs me on principle.) But just now I learned about IndieBookClub, which (like micro.blog) provides an interface for posting—in this case your reading activity—to your own website.

As a non-tracker from way back, I’m probably not likely to become a tracker just because there’s a new cool tool for tracking, but you never know.

Edited to add: I have posted my first book.

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:

Looking up

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.

My Stetson and Tilley hats

Years ago I had a panama hat that was great for hot sunny days. I think I still have it, but after a few years the straw cracked in the crown and I had to retire it from regular use.

For years I made do with felt hats, which are also great, but not ideal for hot, sunny days. So last summer I went to the local Rumours Hat Shoppe to look for a replacement panama hat, and found this hat—a panama hat as re-imagined by Stetson:

Me at Bryce Canyon

It’s a great hat, but it turns out not to be the right hat for hiking in the desert. (It’s more for sitting on the veranda and looking out over my plantation.)

In particular, the Stetson panama hat doesn’t have a cord to keep it on in the wind.

So, after a blustery day at Zion Canyon made me concerned about losing my hat, I visited an outfitters shop in Springdale and purchased a Tilley hat:

Imperfect camouflage

I’m simply delighted with this hat, which does have a cord, arranged so that it can go both behind the head and under the chin, but which can be easily tucked away inside the hat when it’s not windy.

Hopefully I am now all hatted up for years to come.

Learned something new

About three weeks ago, just a few days before heading out on our vacation, I noticed a black spot in the vision of my right eye, modestly to the right of the center of my vision.

I hustled to the optometrist, who dilated my eyes, looked inside, and said, “Yep, I can see a thing that matches what you describe.”

Two things I already knew:

  • Your eye ball is filled with a fluid called vitreous humour,
  • that fluid shrinks as you age.

But in my brain that fluid is rather more liquidy than it apparently is in reality. In my actual eyeball, that fluid is so gelatinous that it is attached to the retina with strands of connective tissue. My vitreous had shrunk enough that one of those strands pulled free, and the strand (connected to my vitreous and no longer connected to my retina) is what I’m seeing. Or rather, the shadow of that strand is what I’m seeing.

They call it a floater, but this one is unlike other floaters I’ve had. The other ones floated—that is, they moved around. This one is fixed in place. The others were also translucent, whereas this one was black. Looking out was rather like using a screen with a few dead pixels.

The prognosis is good. The black spot should become less noticeable, through both my immune system scavenging up the no-longer needed connective tissue and my brain learning that there’s no information in the black spot and filling in with detail from my other eye. (The spot is already turning browner and translucent.) There’s a slightly increased risk of retinal tears and detachment, not from the floater itself but from the shrunken vitreous.

I asked if there was anything I could do to encourage the vitreous to regain it’s original size, but apparently there isn’t anything known to hep with that. The doctor said that it was often recommended that people refrain from heavy lifting, and I actually did quit lifting during the couple of days before the trip and the duration of the trip itself, but I’m certainly not going to give up lifting.

Because of my tendency to worry about such things, it was kind of daunting to have this happen right before our long drive, but in actual event was a non-issue. I’ll update if anything more comes of it.

Monkey bars

I used to play on the monkey bars all the time when I was a kid. My mom encouraged it. She knew it built upper-body strength, and that the ability to traverse monkey bars was an important capability for any human. (She could traverse monkey bars herself, when I was a boy.)

I quit doing the monkey bars, probably when I was college age, and quickly lost the capability. Then for three decades would have been afraid to even try, because I’d definitely have hurt myself. A few years ago I wanted to regain that capability, so I started looking for monkey bars to practice on, and found that they’ve gotten quite scarce. Many playgrounds don’t have them at all.

Winfield Village has a playground in every quad, but the only playground with any sort of monkey bars is the big one close to the office, and it has a rather strange curving monkey bar that over the course of 5 rungs makes a 90° turn—a particularly challenging version. (Like most these days, this one has weird triangular bars hanging from a single support, rather than a series of rungs supported on both sides.)

Bars for brachiating at Winfield Village playground

The reason for both the near disappearance and the switch to triangular bars seems to be that monkey bars are “dangerous.” Many playground safety experts recommend that monkey bars be excluded from playgrounds altogether, and I think the weird shape is designed to make them harder to climb on top of, in the hopes that kids would then not do so.

I spent a chunk of yesterday afternoon at an “alignment play day” with folks from CU Movement (and  kids), getting some hanging and balancing and barefoot walking on various textures. One thing I did was traverse the monkey bars at Clark Park in Champaign—an old-style set of monkey bars, rather like the ones I remember as a kid.

One of the kids in our group—small enough that it was a challenge to reach the next bar, and at a height that the experts would no doubt claim was “too high” for a kid of that size—did the monkey bars, and then immediately wanted to climb on top of them. He asked for help getting on top, which his mom declined to provide—except that she pointed out that one of the supporting poles could probably provide the necessary foot purchase for him to get on top on his own. And he did manage to find two ways to get up there. Having gotten up there, he decided against traversing the top of the monkey bars, and simply swung back down under them.

A new school of thought is emerging (finally!) that “dangerous” playground equipment offers valuable opportunities for kids to do exactly what this boy did: evaluate a hazard and decide how much risk was appropriate. The only way to learn to make that sort of evaluation is to actually practice it. Making playgrounds so safe that children cannot hurt themselves reduces their opportunity to develop a good sense for what is safe and what is dangerous, and what is and is not within their capability.

It has also made it a lot harder for me to find a set of monkey bars to practice on.

I crossed the monkey bars three times in the afternoon, but I forgot to attempt my next big trick: Cross from one end to the other, turn around (without putting my feet down) and cross back again.

I’ll do that next time.
