I have been a napper for 25 or 30 years or more - when I can. I find it a very civilized practice to close my eyes for a few minutes or more each day - long enough to feel revitalized but short enough not to trash my day. Turns out it's good for us after all. The BBC reports about a study done at Berkeley in the US that confirms my personal experience. They say, "A nap during the day improves the brain's ability to absorb new information." Yay.
