Honestly...I'm unsurprised. People have been trying all kinds of shit to enhance their stamina. We want to be better, faster, smarter, stronger, and more virile...its only natural that there are some of us who go to insane (and patently disgusting) lengths to try and make that dream a reality without doing any real, hard work.
Or, as my programming teacher put it, "Laziness is the mother of invention." Never said anything about that "invention" not being something that'd make it hard to keep your lunch down...
