Moreover, it's a difference in the right direction, because most people's
internal clock free-runs (if deprived of external synchronizing effects)
at a cycle length of about 25h. This is part of why it's so easy to stay
up later and later and so unpleasant to get up earlier and earlier.
There was at least one experiment lasting a few months in which two men
tried to adapt to a 28-hour schedule. The younger man succeeded; the
older man couldn't quite manage it.
