@polarisera @HebrideanHecate @stingray @Piss_Ant Yes, I read quite a bit about this years ago. We're designed to carry a light load of parasites -- one researcher gave himself worms and another walked barefoot through latrines in Asia -- but not a heavy load so people have always had traditional methods of keeping parasites in check. I never dismiss ideas as ridiculous, but keep looking for more information.
