Are these guys brave or are they...?

There is a bunch of folks who believe that medication of any sort is an abuse of nature's purity that is human body.

Here is a mild example. A guy I know has the flu.. no not the swine one, the common variety, yes, the common /mild flu or whatever one calls it.

He had been suffering and coughing like a dying man for the last several months. One day I took pity on him and asked why his medications are not working. To this he responds with this proud look on his face as though he had just climbed Mt.Everest without even as much a rope in his hands..

"I don't take medications.."

I don't know If he expected me to look at him in awe, but my reaction was

"wonderful.. folks, lets give this guy an award for not taking medications.. " I was furious

Not only was this guy torturing himself, well am not furious about that, but I was furious because he had been coughing his life out in office spitting out god knows what germs into the air for months putting everyone around at risk.

Well, you might ask, what big of a risk, flu is.

But, my question is, however mild an infection or disease might be, why risk someone with it? Why?
