I really envy you mutants. I'm at the opposite end of the spectrum. I need ten hours of sleep (not like I ever actually get that much) and tend to stay up half the night. No matter how early I fall asleep I still won't be happy waking up before 9 (not that I usually manage to avoid it). What I actually need is a 28 hour day, and since days are 24 hours if left to my own devices my day rotates around later and later. And sleeping all day and being awake all night is boring. Everyone is asleep and shops are closed and everything.
