Professor. I often get up at 9 and go to bed around 1.

That is the key question, are humans really unable to go to sleep earlier? (It certainly wasn't the case in the old days before electric lights and TV.)
I'm definitely no teenager any more, but I normally get up between 6 and 7 AM. Without an alarm clock. And I think the morning hours are the most productive for me.
There are all sorts of interesting facts about sleeping. People used to sleep for 4 hours, then get up in the middle of the night, and then go to sleep again.
Having said that, there is also new research about traditional peoples: http://newsroom.ucla.edu/releases/our-an...ght-either
High school students think they're busy and so they will tend to stay up past 11. (What I've found since then is that at stage X you always think you're busy but then somehow stage X+1 is even busier...)
