My wife used to tell me that kids should be asleep by 2100 because some study showed it is better for them. But what does 2100 mean? It is totally arbitrary. I could accept a study that would reference sunrise/sunset but a specific time?
I would always ask her "is this winter or summer time?" just to show how this does not really make sense. Other times I would say "what if we lived right at the point where a timezone changes?". A few meters difference means 1 hour difference. Which 2100 is the correct one? Or what if 2 people live in the same timezone at the opposite ends of it?
I believe most of these studies are performed in the USA. I have never lived there (I am in Greece, have also lived in Germany) but the feeling I have from some movies and shows is that there are places in USA where the sun comes up at 0500, maybe earlier (and accordingly also sets early). I do not think that the sun ever rises that early here (I actually just looked, throughout the year the earliest is ~0600 summer time). It is only natural to also have different habits on when to wake up/go to bed. And also 2100 (or whatever other time) to mean something else entirely.
