My best friends when I was young were always doctors. I used to dress up in a white gauze helmet and go round and see babies born and cadavers cut open. This fascinated me, but I could never bring myself to disciplining myself to the point where I could learn all the details that one has to learn to be a good doctor. This is the sort of opposition: somebody who deals directly with human experiences, is able to cure, to mend, to help, this sort of thing.
