The latest research shows that the right amount of sleep is very personal and should leave you feeling energized the next day. I'm a sleep doctor, and I've been a 6 ½ hour-sleeper my entire adult life.

A lot of older people think they need less sleep, but in most cases, that’s not true. They may sleep less at night, but that’s because a lot of them take unscheduled naps during the day.
