<a href="http://www.kuro5hin.org/story/2006/4/30/91945/8971">This</a> story about a guy infecting himself with hookworms to cure his asthma is pretty interesting. It has everything: Worms, exotic locations, worms, walking in feces, worms, violent coughing, worms, and worms!

It's the kind of thing that makes me really happy there's an Internet.
