I like to ask retired folk what they like best about not working, and sleeping in comes high on everyone's list. I even had a volunteer last year who told me that since retiring from a job that required a long commute and an early start, I shouldn't count on her for anything before 11 a.m.
I'm energetic long before 11, but I do find that I am no longer rising at 7. Without the alarm clock imperative, it just feels right to listen to one's body and mine tells me that 7:30 is good enough.
But not today. Today I worked a morning shift at one of our branches, so I was up early and on the road by 9. It was OK. I didn't mind it but only because I don't have to do it again until next Saturday.
I am beginning to think that a lot of working people must be sleep deprived.
