1. I've never done this. Not as a child, not as a teen, and not as an adult. I'm nearly 40. I can get myself to wake between 9 and 10 with an alarm, 11 or noon without.
2. I live too far north for this to be reasonable. December days are around 4.5 hours long. Summer nights don't actually get dark here. The sun goes down and stays just below the horizon, so there is a few hours of twilight. You can read outside if the sky is clear.
