There’s a reason there aren’t eyes in the back of your head … so you can see what’s in front of you, so you can look forward to something, because you move forward, not walk backwards. Moon-walking is the only time moving backwards is cool.
There’s a reason your head is on the top of your body … because all actions are first clothed in a thought. Mr. Potato Head can put his ears, eyes, nose, and mouth on different parts of his face but can’t detach the head itself.
