Somebody throws a ball in air and you catch it. If I ask how did you do that then a typical answer would be that you knew where the ball was going to drop and you positioned yourself in a way so you can easily catch the ball. If we see the science behind this then there is a different answer to it.You are through evolution capable of performing this act. Your ancestors had similar experiences and your body is adapted to performing several calculations at once, some conscious and some unconscious ones. . . . .
