People, figure it out already: the Fecal Transplant thing is some pathetic TROLL screwing w/ your heads!!!
Seriously... We send shit (things) to Mars in this day and age, but we're unable to get a purer probiotic than other people's shit (faeces)?!?! YEH RIGHT!
ALSO... consider for a second the vast spectrum of possible diseases that opens you up to. Hell, it's worse than giving an unidentified and untested blood transfusion to the immunocompromised! And, while you're at it, try and recall the fact that *everyone* has a vast amount of diverse fungi living in 'em, just most people's immune systems keep 'em at tolerable levels - ours DON'T.
Eat someone's shit? Other than the ICK factor, you're highly likely to acquire some new strain of fungus (Aspergillus of some kind, C-'s tropicalis krusei etc), HPV or HHV, and a hepatitis or two...
Hell, if your immune system is buggered up enough, you might even get some disease the donor NEVER HAD, but was simply immunized for w/ a different strain than you, or got an optional shot for... If you were born in a NATO country after 1970, do you wanna experience SMALLPOX?? Just eat ANY Eastern European's shit, cuz we still got the shots while you didn't! Hell, I'd mail you mine, but the Russian criminal code frowns upon postmarking any and all biologicals :)
