I find it far more awesome, wonderful, that creation; our appearance in the world; should be the culmination, or at least one of the latest products of 3,000 Million years of organic evolution, than a kind of country trick, taking a rib out of a man's side in a trance.

There's a small worm called Loa Loa Filariasis. This parasite can survive in one environment exclusively- namely, underneath the skin and inside the eyes of human beings.

The worm can actually live in the host for 17 years before the host finally dies.
