hope you don’t mind if I sit this one out

Looks like I’m staying home alone until a vaccine comes; it’s what I mostly do anyway, though I miss the weekly card games. As a libertarian, I do not presume to know what’s best for others. So, lucky me, I need not obsess about policy.

vision imperfect

This morning I saw a series of flashes (both bright and dark) in my left eye, along a peripheral arc. They’ve stopped for now but I also have some new floaters. I have a recurring urge to clean off the spectacles I’m not wearing!

hidden dragon

For years I’ve occasionally had a mysterious itch at my lowest left rib, nothing showing on the skin. Now it has spread rightward at the same altitude, making me think: could this be mild shingles?

two links about medical policy

blogpost on medical licensing

surprisingly sane Atlantic article on the structure of the health biz

Update: Twice in 2018, people urged me to improve this page by adding links about addiction and vaping.  If it happens again, I’ll suggest that they do so in the comments.

I’m melting!

Without serious effort, I seem to have lost a tenth of my peak mass in three years. I think the main change is that I no longer eat rice most days.

unexpected aspects of asymmetry

My left arm is very sore today, making me notice how many little things I habitually do with my ‘wrong’ hand. I wonder whether this says something about my brain.

They say women’s hemispheres are less specialized; maybe my partial ambidexterity, the weak dominance of my left eye, and the sparseness of my body hair are all related.

chaos and health

In a private forum, Rafal Smigrodzki wrote:

I remember that one of my early epiphanies on the road to libertarianism came when I was reading about chaotic, scale-independent oscillations in heartbeat frequency. One might naively think that the healthier the heart, the more regular its beat – but actually the opposite is true. A healthy heart chaotically wanders around a setpoint, as a result of interactions of millions of locally coupled oscillators, the spontaneously spiking cells in the AV node. But as you press your heart harder and harder, as in heart failure, the chaotic rhythms are becoming simpler, until one last AV frequency remains, usually quite high, tachycardic, produced by an ever smaller set of cells. The next step may be fibrillation, or asystole, and death.

So, in our hearts health comes from chaos, the absence of a rhythm for every cell to dance by. Networked interactions can be made much more robust using multiple, locally interacting oscillators, rather than relying on a single one. The analogies to the society, the share of activities controlled by a single global decision-maker versus multiple local ones are in my mind crystal clear.
