Personally I agree. I'd also find it interesting to see how removing sleep from our lives would effect things like depression or even how it would just effect people having a bad day. For example if I'm having a terrible day I can't wait to get into bed, fall asleep and end it. The separation sleep provides between one day and another gives the feeling that tomorrow is a fresh start and the problems of today might be less. I'd guess I would be miserable for longer without sleep.
