I think most cases are going to be like that, but people with "advanced" or "delayed" sleep phases are not in the same boat - they will have trouble adapting to any fixed schedule, and no matter what they choose they will feel "jet-lagged" after a while as their "natural" sleep phase goes out of sync with it.

Yeah I definitely think there are probably some people like this with messed up cycles that they can't do anything about it. But in general, it does kind of annoy me when people who are late to stuff in the morning blame it on being a nite owl, kind of disposing of any responsibility as if they have a real medical disorder or something when I think for most people it has more to do with enjoying doing stuff late at night or just getting in a habit of staying up late from trying to stretch the day before having to go to work.
