"If you are exposed to bacteria all the time your body will develop a natural resistance. That's probably the reason why tourists get sick all the time in third-world countries though the locals have no problem with the food and water."

That is probably EXACTLY the reason, in many cases. The people are probably full of parasites, too. Unless the chemicals being dumped on the areas have killed them off...

But there is a line between need and stupidity. I don't have TV, so naturally I don't see these shows, but this guy sounds like a real fool. And the people watching him from their sanitized world are probably going to "do as he does, not as he says".

I do miss Discovery and the History Channel, though...
