I'm blaming it on my pillow

I'm wondering if it's true that some people can get by on 4 hours' sleep.  I almost always wake up after 4 hours, let my brain churn up all the things it wants examined, get up if I can't get back to sleep and unless I actually put my mind to "napping", I'm up for the day.

I'm not sure why, but napping has always been anathema for me.  It seems wrong to be sleeping when you could be reading or cooking or walking.  I know that a lot of people use napping as a way to recharge.  I just don't seem to need the recharging.

Is that because I've got a lot of seemingly unnecessary energy, or because I'm not active enough, or is it because I am blessed/cursed with what my Catholic parents called The Protestant Work Ethic?

I think I'm doomed---too awake to sleep, too guilty to enjoy being shiny, too conforming to just accept myself.

Still, I've got a couple of hours to crochet a hair shirt.
