How much sleep do we need?

Do you know there's an app on the iPhone which will inform you when its time to sleep to get enough sleep for the following day? It has a polite beep when its that time. And the alarm is nice. It isn't the traditional beeping sound which scares you from sleep to awake mode in 5 seconds or less. It's a non-intrusive tone played softly and crescendoing as the time goes on.

This week has been busy. I am officially sleep deprived and the mood is fragile. What I need is a good 8 hour sleep. Hope to catch up on sleep this weekend.
