i've heard several times that the amount of sleep each individual requires is based on a number of factors, some of which include age, weight, and even diet. everyone has different schedules, and each one is independent to one another depending on their own individual health.
i'm not one to set an example, but i average anywhere from 5-7 hours of sleep on a regular basis. sometimes my body requires more, sometimes less, but it seems to balance out and i never feel as though i'm suffering from lack, or over abundance, of sleep.
i've included a yahoo! health article to help shed light on some of your own personal sleep habits.
