Yaroo! Set theory roughly 50% vised (that is, [non-re]-vised). Unfortunately, sleep not going so well. Two hours last night before I got to sleep, thinking about someone I don’t want to think about, and waking up lots in the night.
Also, another mystery: I’m feeling sore in my legs and shoulders and all over, all the time, and I don’t know what it is. I don’t feel all that tense when I’m hunched in the library, and though I am exercising fairly often, I’d expect it to hurt more in arms or thighs or whatever if that were it, or some other muscles I actually use.
