It is Saturday morning — actually, by the time I post this it will be past noon. I slept long and late. My schedule recently changed so that I need to be to work by 6 a.m., so I leave my house at 5:15 a.m. I try to get to sleep by 9:30 on work nights, which would give me 7 hours sleep — plenty. It seldom works out that way, so what I find it is go into sleep deficit during the week, feeling a bit like a zoombie as the day progresses. (Read about sleep debt here in National Geographic article.) By Friday night, I crash and sleep 10 — one night it was 12 — hours. You hear a lot that people say they need less sleep as they age, but according to the National Institute on Aging, that is not true. (NIA does say older people tend to go to sleep earlier and get up earlier, but right now I’m going to sleep about the same time as my 7 year old!…more good stuff on sleep and aging here at NIHSeniorHealth.) I really should get off my butt and get out right now for some exercise, but it is damp and chilly (for Florida) right now, so I think maybe lunch and the paper for me…and a nap?
