The human brain is an absolutely fantastic computer, throwing a ball is proof of that.
You think you can't to advanced calculus or trigonometry? You think your little short bus brain would crap out 15 minutes into a physics 101 class?
Try throwing a ball at a moving target. Whether you hit it or got even close, you just did some graduate exam level calculations in less than a second. Your brain took into account the speed of the object, it's relative distance to you, it's direction of travel, the speed of the ball in the air, the arc of travel of the ball from the effect of gravity, and combined those to estimate the place the target will be when the ball is also occupying that 3D space. Not only that, but your brain also did the math on which way to move your arm to create the leverage and force to achieve the specific speed and arc of the ball you were estimating during the throw. All of that in a matter of seconds or less and you didn't even realize you did it.
Be proud of yourself for even being able to attempt this. Your mind is an incredible thing.
