We have two eyes so we can see opposing views, two legs to keep our balance and two arms to hold those we cherish.
But notice this—just one head. If we had two, they would surely be at odds with one another. And just one mouth; if we had two, we would spend all our time arguing with ourselves.
Are some of us all thumbs? Do some of us have two left feet? Don’t worry about that; it could be handy if the rest of us need some spare parts.
