I completely agree. I'm in my early 20s and struggling a bit with getting up for work at 7am. I'm doing better than I was right after college, but I'm still a pretty solid 2 am - 10 am person. At one point I taught a night class and was full of energy until well after I got home. Wish I could do that again.

The morning people in my life keep telling me to just go to bed earlier. It doesn't work that way! I usually just say they should try sleeping late. They can't do that (and 8:30 doesn't count as "late") any more than I can go to bed at 10.
