No one really knows exactly why we need so much sleep, but it seems obvious that many of us aren't getting enough. Tu veux coucher avec moi? I'm bushed.

Everything You Always Wanted To Know About Sleep (But Were Too Afraid To Ask). Circadiana is a new specialty blog dedicated to chronobiology. As a night owl (I'm posting this link at 2:45 AM), I look forward to many late nights reading this site.

Do Republicans dream of electric sheep? A new study concludes that Republicans have scarier and more frequent nightmares than Democrats. As usual, the explanation for this is split among party lines:

"What do you expect after eight years of William Jefferson Clinton?" -- Kevin Sheridan, Republican National Committee deputy press secretary.

"If George W. Bush were the leader of my party, I'd have trouble sleeping at night, too," -- Terry McAuliffe, Democratic National Committee chairman.

Wow... deja vu all over again.

It's common knowledge that Tetris players often see the game in their dreams. Now scientists are using the game to help understand the very nature of dreams themselves. But it doesn't address the question I've always had: Why Tetris? Why doesn't this happen with Quake or Ultima or even Super Breakout?
