A friend just sent this to me and it is so fascinating, I wanted to share. I went to see a show on the human body a while back. The one where the body was sliced and you were looking at the real thing. Not only was I struck by how tiny the person was, but I recall saying to myself over and over again, "It all looks like trees. We are just like a collection of trees inside!"
