A six-year study of more than a million adults ages 30 to 102 suggests that sleep deprivation is not the health risk some claim.

Psychiatry professor Daniel Kripke of the University of California at San Diego, who headed the study, suggests that the concept of sleep deprivation is a myth pushed by the makers of sleeping pills. "There is really no evidence that the average 8-hour sleeper functions better than the average 6- or 7-hour sleeper," says Kripke.

And he suspects that people who sleep less than average make more money and are more successful. Personally, as I sleep 3 or 4 hours a night, I think this guy's all right.
