  1. There are so many people who have done great things and sleep only 4 hours a day and are healthier than normal. Your sample size study is v small you are not taking into consideration lifestyles tge food they eat the type of weather the people live in the culture and practices of the study group how much exercise did the subject get any underlying genetic disease etc etc. This is quite unscientific when you just make such statements without taking into consideration so many other factors.

  2. Memento is an amazing movie! Still not sure I can fully piece it together, even after wathing it 3 or 4 times. I don't sleep well, haven't since I was a teenager, now in my late 30s I honestly feel like my life is that movie. Just a feeling of being constantly confused, really poor executive memory, groggy when i wake up, sleepy during strange times of the day, constantly forgetful. I wonder if it's an acumulative effect of years of poor sleep. I wonder if that's one of the reasons why old people start to experience mental impairment too?

  3. Ok, but have you examinated what were the results after sleeping too much? Ten hours is worse than eight? Moreover, this speaker use numerous logical mistakes and simplifications, for example you cannot shift experiments in mice to human, or he said that it had happened within a day so imagine what would happen for a week.

  6. Schools start too early in some areas because the working class need to get to work, so the kids aren’t learning at 7:30 they are given breakfast and it’s basically a daycare situation. And so starts a lifetime of sleep deprivation which is tragically unavoidable for many. Adequate sleep has become a luxury. That’s why homeless people are insane. They are chronically sleep deprived. When they do get a bed to sleep in, they can’t relax, they are cramped in like sardines, and they are forced out too early.

  7. My body used to sleep 5-6 hours and i am getting up automatically in specific time, what shall i do to get back as i used to sleep 7 or 8 hours

  8. If the room is still occupied by the same people could Talks at Google consider not cutting of the video?
