Isn't it wonderful that my body knows how to make a baby? Isn't it wonderful that I don't actually have to know the science behind dividing cells, specializing, making lungs, liver, heart, blood, and guts? Seriously, because our baby would be in big trouble if I were in charge of putting him together myself.
See exhibit A. This is some work that I did for El Senor. El Senor provided me with a vector file of a body silhouette and a non-vector file of guts---the stomach, and the small and large intestines. And all I had to do was use the non-vector file to make a vector illustration of the stomach and guts to fit into the vector illustration of the body. (Sorry with my being all technical by using the word "vector"---let's just say that vector work is my specialty.)
So I made the guts and I put them on the body.
And then El Senor informed me that I positioned the rectum at the man's belly button.
Whoops! How was I supposed to know that's a rectum? But thanks to my auto pilot, our little developing baby will not poop out of his belly button.
