 One way to teach something, learning, is to have unpredictability with periodicity, where you have unpredictable things that don't occur again and again. It's not reproducible in a lab, but it happens again and again. And you will remember those kind of lessons, even if you haven't figured out what the heck they mean. Right, right, right, right. So some sort of kind of almost like a training program where we're being conditioned.
