Perhaps you're not like this, but I am: It's the best feeling in the world to go back to sleep. When I'm asleep I'm just sleeping; when I hit snooze, though, I get 30 seconds of "awwww yeeahhhhhhhhhhhh..."

I don't use an alarm anymore because my sleep is so consistent and I don't have a morning role call, but when I did, it was awesome to be able to settle back in.
