I argue with people over this all the time.  When you get up as early as Dale and I do, you need a nap to refresh you during the day.  It's just not good for a person to go all day with just 4 - 5 hours of sleep.  True, I could go to bed early.  But, the best shows and most fun normally happens when the rest of the world is awake.  That's why they call it "prime time."  I would bet that the reason a lot of you that are cranky or on edge all the time is lack of sleep. Here is what the experts say about napping. They even tell you how to nap!

Napping may even help you earn more.  Motivation, productivity even alertness may just help advance you or get that last bit of work done to help you along!
