The saddest thing is how morning persons have managed to make a virtue out of their biological clock and that their preferences are so deeply ingrained in society now.
> it does, you know, make sense to conduct society's business during daylight hours.
Not necessarily! In hotter parts of the world, they deliberately avoid conducting business during the middle part of the day. (That may come with earlier rising, offset by a siesta.)
It's also an age thing. As you get older, your sleep moves in the early direction and you also need less of it (if you're in good health). My dad's 61 and sleeps 9-to-3:30. I seem to be headed in that direction. I'm usually up by 6-7 even if I go to bed at 2:30, so the smart thing for me to do is sleep earlier.
It's biology. Giving it a moral weight is nonsense.
