But now I go to bed at 8 p.m. and I wake up at 4 or 5 a.m. So-

at least two things to know one of which is there is incredible circadian diversity even in amongst family members most of human history we lived in bands of 50 to 300 people and it made sense that there would be vast diversity of chronotypes in our in our tribes right so there would be some people who would be early to wake up there would be some who would be very late to go to bed and and all of which is serving to kind of protect the tribe, if you will.

That's number one.

Number two, and so I would say there's something innate about our circadian rhythm that's worthwhile to know.

Secondly, this very much evolves over the course of a lifetime.

As a general rule, we have a later circadian rhythm, so we're later naturally to go to sleep and naturally to wake up when we're younger.

And you can cue in the cliched teenager description here.
