Sleep is also an interesting example of pathologies in American high schools. Why do they start so insanely early
As long as the "insanely early" hours do not involve starting school before dawn, this is a non-issue. Anyone can adjust their circadian rhythm by just going to sleep earlier, and/or by napping throughout the day in order to compensate for any sleep deficits; we should be raising awareness about these solutions among students. Simply starting school later would not have substantial effects in the long run, anymore than, say, changing to DST, or moving to a different timezone would.

Wait... DST makes sunrises and sunsets later by civil clocks, so I would expect its effects to be quite the opposite of starting school later (and pretty similar to those of starting schools earlier). Did you mean to say something like "abolishing DST" instead, or am I missing something?
