Have you ever noticed that toddlers are champion squatters? They sit into the deep squat with total ease, hang out there for a while, play with some toys, look around aimlessly, eat some dirt, poop their pants, get up again, walk three steps, and then drop down smooth as silk into the deep squat again. And then over and over again, like twenty times in ten minutes, with no sense of effort or fatigue at all....
