We put our backs into our work.
Football players throw their backs into the play.
Our backs ward off the world. We even turn around to face away from oncoming danger. It is a feature of our anatomy that our backs are more padded and more protected from our fronts.

As human beings, we have the anatomy that allows us to be intimate front to front, that is, soft side to soft side.
