Depends how you're built. Not so much advantage. It might sound complete crackpottery to some here, but there's a small percentage of the population that can get by on a very small amount of sleep of less than 2hrs and certainly survive on the ubermann. I'm not quite that bad, but I can easily survive on some of the other 'cycles' it lists there. Pretty much tried all of those or variants over the years. For some people it'd work ish but with tiredness, for others it would not work at all.You very quickly get very tired and learn why they use sleep deprivation as a torture - I cannot see an advantage.
It depends. We come from a culture with a taboo talking about sleep. A lot of people who have sleeping 'problems' are not necessarily happy people their whole lives before they come to terms with it. They think there is something wrong with them, they think they are freaks. They expect certain sleeping patterns and are very unhappy if their body decides otherwise . Some people that do stuff throughout the night, it can be a very, very lonely places for people. It's a very odd world.One o' them being +21hours wakey wakey time
