It's my conceit that perhaps some diseases perceived as diseases that destroy a well-functioning machine actually turn it into a new but still well-functioning machine with a different purpose. The AIDS virus: look at it from its point of view. Very vital, very excited, really having a good time. It's really a triumph if you're a virus. See the movies from the disease's point of view. You can see why they would resist all attempts to destroy them. These are all cerebral games, but they have emotional correlatives as well.
