We seem to be best adapted to squat and hunker, not sit in a chair or even stand straight.<p>No studies that I can find, but when I lived in Asia, older men who gathered to chat, play cards, etc., tended to squat. There were still lots of squat toilets around, too.<p>I'm thinking of building a platform so I can squat at my desk rather than sit on my tush. Alternatively, would like to power my computer by pedaling or cross-treading, but that's probably a bigger project than I have time for.<p>But squatting, that's underrated in Western culture. It feels great; more should do it, and not just while on the toilet.
