Apparently the biggest factor in the amount of sleep we get is whether or not we have a job. Earlier this week, the Washington Post featured an article on a new report, 'Not So Deprived: Sleep in America, 1965-2005,' that found that employment status had a greater effect on sleep than age, race, or sex.
The report also found that Americans seem to be getting more sleep now than they did in 2000. Part of the story may be that, when left to our devices, we tend to underestimate the actual amount of sleep we get.

Do you get enough sleep? Does your job affect the amount of sleep you get? Have you ever taken a nap at work?
