You've not been following your TED.

Lots of folk live happily on way less that eight hours. Whether the folk who mandate that they must have their eight hours are deluding themselves is unproven. I know it's a very touchy subject for those that believe they do.

Lots of people do and lots of people don't. Saying someone who can't go with less then 8 hours sleep shouldn't start a business is like saying someone who can't survive on one meal a day shouldn't, or people with one leg.

I do quite a bit of physical activity. Anything less than 7 hours would soon burn me into the ground.

I haven't seen this ted talk yet but keep in mind that perceived sleep benefit is mostly subjective, so if a person feels like crap if he has no sleep, no amount of evidence to the contrary really matters.

I don't really understand your comment. I watched the clip you linked to and the sleep schedule she states is ideal is 8pm-midnight and then 2am-Dawn(3-5hrs). This comes out to 7 to 9 hours a night for my area, depending on the time of year.

I think it just depends on the person, I'm sure there are people who do just fine with 6 or 7 hours a sleep on average per night but If I don't get 8 or close to it I do suffer (there probably are people who need 10 hours a night as well). The suffering however isn't instant it may even take a day or two to catch up but it is noticeable.

I thought the video was very uninformative. Plus, she claimed that the test subjects still slept 8 hours. It's just wasn't continuous. What was your point?
