Do we overestimate how much sleep we need?

By studying the habits of three hunter-gatherer groups who live much the way humans have for thousands of years, a team of scientists is challenging conventional wisdom about how much sleep we need. Hari Sreenivasan goes to UCLA to learn more about getting enough rest and to do something he's never done on assignment before: falling asleep while on the job.
