When I was in a college I had one term where all my classes were in the morning. I slept 3-6 am then 3-6 in the afternoon. Never felt better.
p.s. this guy and his 28 hour cycle sounds FOS to me. Millions if not billions of years of evolving towards a 24ish hr cycle and somehow he gets a mutant circadian rhythm that's FOUR hours off? Gtfo please.
