Once upon a time there was a head. Just a head. By sheer force of will—or maybe it was some kind of psychokinetic energy—the head was able to move itself around, open doors, pick things up. In fact, the head could do just about anything you or I can do.
And to hear the head tell of it, life is pretty good when you’re a head. No stubbed toes. You never hit your funny bone. No love handles. No stomachaches. No tense shoulders.
Of course, there are also no dips in a hot tub. No lazy days in freshly washed sheets. And while the head could eat food, and taste it just as well as you or I, it could never feel satisfied and full. After a while, the head came to realize that it was incomplete.
So when one day the head saw a body that had no head of its own, the head got really excited. It floated over and suggested that the two might get together. Of course, the body had no ears, and could use only body language to communicate, but eventually the two of them made a connection. And when the head felt what it was like to have a body, and the body felt what it was like to have a head, what else could they do? And the two have been dancing through life ever since.
