Sign me up. People has had depression cured from a poop transplant.
Mice given probiotics and placed in a tub of water were shown to swim twice as long as mice without in a behavioral study designed to test learned helplessness. To confirm it is indeed the probiotics communicating with the brain, they severed the nerve from the brain to the gut, the vagus nerve and the probiotics behaved like the mice who didn't receive probiotics.
The lining in sausage is made from the intestines, so depending on how well they clean it, there probably is some poop in sausage.
Are you srs?
I believe it's called a fecal transplant.
