Well, let's say you sleep 6 hours a night, and some one asks you: "If you slept 2 hours less each night, image what you could accomplish with that extra two hours every day. Just start sleeping 4 hours a night and eventually you'll get used to it!".

For some of us 10+ hours is a biological necessity, I've tried forcing myself to sleep exactly 8 hours a night for two weeks at a time and it destroys me mentally, every waking hour is torture because I'm so sleep deprived.

Most (all?) people are productive every waking hour. I imagine the people who need 10 hours each night are getting those extra hours from time they would have normally been watching TV or some other daily entertainment and not from their working day.

I vary from 6 to 10 hours depending on the season. It averages out.

I bet a lot of them are unemployed. This survey should really be correlated with how many hours a day the person in question works. It's very likely those who can afford to sleep longer have to work less.
