Look, as a Medical student, I agree with what you are saying regarding the challenges that faces solving such a problem.

But, being stupid help solve BIG problems. This guy is risking his health for the sake of science. He has a very high risk/reward ratio. I don't think he is not serious. He is not even trying in animals (which I thought he was doing before reading the rest of the article). He's obviously stupid when it comes to experimentation, but this is when it yields interesting results.
