I somehow managed to not not know until now that there were sweat glands on my fingertips. I guess they seemed like the dry spot relative to other more productive areas. And now somehow I’m too aware of this new fact and am worrying about fingertip sweat on everything.

Chimpanzees also have fingerprints, and they also prune up if they’re wet for a while, like human fingerprints do. It’s apparently helpful for hanging onto wet tree branches. Think of it as the leftovers of Evolution In Action.
Sweaty hands you say?

Crime is crime.
Excretion is excretion.
That is all.
