Workout

My knees were bad much of yesterday. They were quite a bit better today, but not perfect; as I left work, I concluded that they would probably hurt a little no matter what I did, so I might as well go to the gym. (If I'd thought they would hurt only if I exercised, I probably would have waited until tomorrow.) I was careful, and the stairs down and up don't seem to have caused trouble. (This was at the gym near my office, but the elevator was broken.)
