Recently I find that I need more and more sleep. I still remember the days when I had a full-time day job as an engineer and a part-time night job at a restaurant as a buy boy; there's just no way I can do that anymore now. Every night I need at least 8 hours of sleep in order to function okay at work. I feel that it's a lot despite the common belief that 8 hours is normal.
Is the standard of 8-hours sleep normal or a myth? I really don't know. If you have a few seconds, I would appreciate that you participate in the little survey on the right hand side so that we can have a rough idea on how many hours people usually spend on sleeping. Thanks a lot! :)
