Sleepless nights can cause worse problems than grumpiness

Confession time: My husband has actually uttered the words "I'd rather take a nap than have sex." Is our marriage on the rocks? No, like 75 percent of adults, our problem is sleep -- he has insomnia; I snore.

We seem to be too busy to get enough sleep. On average, Americans sleep roughly 7 hours a night, 1 to 2 fewer hours per night than they did 40 years ago. And when we do hit the sack, sleep doesn't necessarily follow. No wonder my husband and I sometimes feel like zombies. Worse, there could be serious health repercussions due to our lack of shut-eye.
