Idk really, but everyone gets up some time at night... and when unable to return to sleep turns to the internet, dont we... sometimes=). Ah, but being an early riser, i strive to be in bed at 9 or 10. That isnt always possible of course, and when very tired and i was just resting at, say 8, i find i have dozed off and wake up at 10 or so again, to finish stuff i meant to earlier!
