{{B}} More Than 8 Hours Sleep Too Much of a Good Thing{{/B}}
Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences.
Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers.

Before you argue with your boss, check with the boss’ secretary to determine his mood. If he ate nails for breakfast, it is not a good idea to ask him for something. Even without the boss’ secretary, there are keys to timing: don’t approach the boss when he’s on deadline; don’t go in right before lunch, when he is apt to be distracted and rushed; don’t go in just before or after he has taken a vacation.
