Actually, I once read, from a steemSTEM author back in the day (is this showing my age?), that the best defecating position is the squatting position! And the author was associating a host of gut and other health problems with the modern sitting position, and was suggesting as a solution using a stool in front of the toilet seat to raise your legs, so as to mimic the squatting position. Your post kinda corroborates what he was saying! I think the guy was Nigerian too, dunno if it could actually be you! Squatting or some such does seem to make sense for birthing, since that would allow gravity to do some of the work.
