　　American society does not treat nap(-FBI) friendly. In fact, says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine. "There's even a prohibition¹ against admitting we need sleep". Nobody wants to be caught napping or found asleep at work. To quote a proverb: " Some sleep five hours, nature requires seven, laziness nine and wickedness eleven.
　　Wrong. The way not to fall asleep at work is to take naps when you need them. We have to totally change our attitude toward napping", says Dr. William Dement of Stanford University, the godfather of sleep research.
　　Last year a national commission² led by Dement identified an "American sleep debt" which one
　　member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, president Clinton is trying to take a half hour snooze (-JB-SS) every afternoon.
　　About 60 percent of American adults nap when given the opportunity. We seem to have "a
　　midafternoon quiet phase" also called "a secondary sleep gate". Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap. We superstars of snooze don t nap to replace lost shut-eye or to prepare for a night shift. Rather, we snack on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats; on floors and beds; and in libraries, offices and museums.
