We probably don't have a will either. "Will" is just a well orchestrated illusion perpetrated by a collection of cells. So, each individual cell has a potential for many different kinds of existences and we are bending their existence to our "will" so the net effect is an opportunity cost of that cell doing something else. If I was a cell I would want to be a penis nerve cell that never encountered VD. 
Or maybe a brain cell in the pleasure center of the brain. Imagine being forced to be a skin or fingernail cell! The humanity!
