Quote by: another day  Waste time? Time for what? We all die eventually. Time is only useful if it aids in your survival, which sleep does. Thus sleep is no waste of time. |
Survival is basic, but humans can spend time enjoying things and doing stuff that makes us happy, once survival is not our main objective in life.
Concernng sleep, the best survival method is to learn how to be a lite sleeper instead of a deep sleeper. Such that our senses of hearing and smell can act as alarm clocks in an emergency situation.
Hibernation is also a cool idea for long term living in adverse weather conditions. Bears snooze in the winter when food supplies are low, frogs and hibernate in deserts for years until the next rain spell comes along. Humans have failed to evolve that evolutionary advantage,
But we could freeze your body instantly while you are in a deep sleep and then thaw you out 300 years later, then you could claim a long survival rate. Unless someone forgot to do that 300 years form now.
