Many of the toilets in this part of the world, particularly in China — even the ones in touristy places like museums or the airport — are of the squat variety. If you’ve never encountered one of these things, it’s basically a porcelain hole in the ground.
Proponents will tell you that squatting is actually a more natural position than sitting to do your business, and maybe that’s right, but I just can’t do it. There are so many ways it could go wrong.
I actually came close to being desperate enough to use one at one point– but then I had a grim, Dead Zone-esque premonition in which I lost my balance mid-squat and fell over, and that was that.
