I have been hearing about this raw water movement. At first I thought it was a joke but then I started seeing articles about it.
What made me think of this is what I saw yesterday. It was a tape worm in some poop I found in the woods. So if you would like tape worms and parasites to live in your guts. The raw water movement is for you.
