To Squat or not to Squat

So this is the (in)famous Chinese squat toilet. Almost all the toilets in China are like this. Only a few places, such as the Beijing international airport and foreign teachers' (like mine) apartments have western-style toilets. It is of course very good for your elimination to use such a toilet since it forces you into the "primitive man" pose whereby the fecal matter can excrete much more efficiently; this pose is physiologically correct way to move the bowels and is of course much cleaner since your ass does not actually touch anything. You almost need not use any toilet paper when defecating in such a position (ever wonder why dogs and cats don't need to wipe their butts?); perhaps this is why I never see toilet paper in Chinese bathrooms? However, I don't think this toilet would be a big hit in the US of A for several reasons: (a) Americans are used to having copious reading material by their toilets at home and this precious reading time would be gone, (b) the American diet often leads to constipation and this toilet definitely works your leg muscles and one would get very tired if the shitting took too long, and (c) many Americans are very fat and would fall in the hole after a few seconds of squatting.
