"we never used to have all these women in their 30s suddenly getting diagnosed with ADHD"
listen, I wouldn't have even noticed I have ADHD if I lived in an era where my doctor could ask if I want to lose 5lbs and then hand me enough amphetamines to see the face of God
and when our ancestors slept in trees I bet having a few ppl who stayed up late and were easily distractible by noises made a huge difference with leopards
I read an anthropology article about the !Kung people and their sleeping years ago. Over something like 5 days, there were only 11 minutes when everyone in the village was asleep.
We all have our places in the world, just not necessarily in an industrial society
I hadn't seen that, but it fits well with my theory about morning people, night people, and people like me with bifurcated sleep patterns.
If you live in an extended family group of 20, including small children, it works better if people are alert at different times.
Neither I nor my dad are the type of people who'll willingly get up before about 8am (I *have* to, he doesn't). But when you're a farmer you set your own hours, so what does it matter to him? If he's out working until 9pm instead of 7, there's no petty boss-type yelling at HIM!
