We're talking this morning about sleep - why we do it, why we can't seem to get more of it.
Yesterday, WEEKEND EDITION's Scott Simon chatted with a comedian who has his own sleep troubles. Billy Crystal writes about them in his new book, "Still Fooling Them."
SCOTT SIMON, HOST:
Has insomnia been an important part of your life?
BILLY CRYSTAL: I've been up since 1948.

CRYSTAL: And I'll tell you why. My first seven days on the Earth, I must have broken sleep records. I'd 20 hours. I'd go 15, 16. But then...
SIMON: Yeah.
CRYSTAL: On the eighth day, somebody with bad breath and a beard grabbed my penis and cut the tip off. I've been up ever since.
(LAUGHTER)
SIMON: I hope that was a mohel.
CRYSTAL: I think somewhere in the back of my mind that I think someone's coming in to do that again.

But it's true, I'm a restless sleeper. My mind is always going. I'm always thinking what I need to do, what I haven't done, what I did do, what I didn't do as well as I could - I'm relentless that way with myself.
