The History of Sitting Down (1967) (books.google.com)

I will check back to see. Is not squatting bad? As in chairs are a technological de-evolution?

I used to get scolded for slouching, but bullies slouch. They seek the endorphins of slouching. I sort of slouch like a plank, or maybe it is lazy & even more inert than regular sitters. I'm not sure.

Seems like a cool book! There's an interesting note on page 280 about how wealthy people and their apprentices used to live in the same households, but began living separately as cities became larger and began to separate areas of working from living. Compare this with the huge migration of workers in countries like China today, where people work far away from their homes and families.
