Even a good night's sleep doesn't totally compensate for many weeks of sleep loss. And it's the late-night period when the accumulation of sleep loss may be most apparent. Researchers at Brigham and Women's Hospital examined the effect of weeks of insufficient sleep on performance. They scheduled nine healthy volunteers to live for three weeks on a schedule consisting of 43-hour periods in which they were awake for 33 of those hours. That equals about 5.6 hours of sleep for every 24 hours.

If sun worshiping is still a must, so is sunscreen, most doctors say. Now, some researchers are crying "overkill." Getting a little sun, they claim, isn't a bad idea.

BOOSTER SHOTS Life is a road strewn with potholes, wrong turns and tree limbs sticking out at eye height. Don't I know that. But some would argue the hazards are more plentiful and to be found in unexpected places. A PR agent tried to convince me that we are riddled with disease for one principal reason: We eat too much calcium.
