Stool, feces, excrement, dung and even poop. It doesn't matter what you call it, you're doing it every day (I hope) and you're probably doing it wrong.
It turns out that all the countries that have fancy, sit-down toilets aren't allowing the... uh... 'hatch' to open all the way.
When we stand up or sit down, there's a kink in our lower gut that stops us pooping at random. But when we squat, our guts elegantly straighten out, leaving us free to eject any waste in comfort.
