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.
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.

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.
I reloaded MacOS, restored my home directory from backup, and was surprised to learn that I have 3e5 files. Most of the bulk is music, but that’s only 7e3 files. Is there a tool analogous to
du that gives the number of files in each directory, rather than their aggregate size? —Later: When Apple Mail imported my Thunderbird archives, it made huge numbers of files, but I don’t know yet whether they’re enough to answer the question.
In other news, the medical jargon specimen of the week:
Infant is status post a negative rule out sepsis workup . . .
I guess that means sepsis was ruled out, rather than that it was not ruled out. The weird thing is that “rule out sepsis” is often listed as a diagnosis rather than a procedure.
Hey, I’m a fictional character! Dr. Anton Sherwood, “an older man in a tweed suit”, appears in The Secret Hour by Scott Westerfeld, a novel about which I know nothing else. (I searched for my name, as one sometimes does, this time looking for ones that aren’t me.)
The latest thing to puzzle me in med-speak is “benign yet appropriate”. When would it be inappropriate to appear healthy?
There apparently exists a surgical tool called a synovial elevator. Makes me think of a bioengineered building, with beams of bone.
