I rarely sleep more than 6 hours, never have. I wake up at 5am naturally and I'm awake. There is definitely a difference between people who are "getting by" on little sleep, and those of us who need less than the "usual" amount. I seem to need less as I get older, and less the more exercise I'm doing (I'm a distance runner) which doesn't seem to make much sense, but there you have it!
