I'll throw this in the pool, personal anecdote. I have 2 children, school starts at 845 and it's within a 15 minutes walk. We get to sleep until 745,which is great. Our bedtime is always the same 8 in bed, about 830 asleep and for the adults between 1030 and 11 (I need 9 hours). As you can see pretty consistent sleep schedule. My sleep is somewhat disturbed, as in I wake up a minute 2-3 times per night. Not alwaya, but frequent. Last time with new year (no alcohol), I went to sleep at 3 am, and I forgot how good is it. I'm a former night owl, at 3 am ny body feels tired, it takes zero effort to sleep, I closed my eyes and I passed out, deep sleep for 6 hours, the use washroom and another 2 hours of sleep. It was incredible. Society doesn't allow that, but the difference between "have to go to bed" and "go to bed when ready" is huge
