When you're in your twenties, you could eat styrofoam and still function appropriately. I like to believe I can still do what I used to do in my twenties...just can't do it as often.

A twenty minute nap in the middle of the day is hugely beneficial. Just enough to not get into deep REM. I read somewhere, maybe it was apocryphal, DaVinci or Michelangelo would doze off with a spoon in their hand, over a metal platter. When they were just about to fall into deep sleep, the spoon would fall out and hit the platter and wake them up.

We don't NEED caffeine but in moderation it is no more detrimental than working at your desk. http://www.informationweek.com/news/hardware/showArticle.jht...
