I get perhaps 5 hours of sleep a day. It seems to be enough. Long ago,
when I was young, that never would have been sufficient.

I also seem to need less sleep than when I was younger. OTOH, I'm less
inclined to try to get by when I haven't gotten enough sleep. I'll lie
down at any time (when I'm quick enough) and fall asleep at any time!
