I'm getting old.
I'm not 30 (quite) yet, it's 11 o'clock, and I already feel like it's past my bedtime.
Gone are the days when I would pull an all-nighter. Fortunately, though, the need for such things has long past. When I leave work at 5 pm, I don't think about it until the next morning.
Instead, I fill all that time with crochety old-man-type activities. I just did the crossword puzzle, and I read the newspaper stories about the Middle East.

Pretty soon I'll have a bald spot, reading glasses, and slippers next to the bed.

Old, old, old.
