Curious to learn which lifestyle factors correlate with extremely regular sleep patterns. Of my friends who have very regular sleep patterns, they tend to be very stable, long termists, career focussed, good in relationships, at least moderately sociable, fit and healthy (although in no way obsessed) and well rounded. Kinda good at everything but not extreme in any way. I'd guess those factors alone would have a noticeable effect on longevity.
