Holy crap, Batman! Your shit is actually alive! Full of oodles of wonderful virii. Positively swimming with gazillions of bacteria. Saturated with armies of protozoa. Crawling with countless little wormies. Don’t eat that shit! Whatever you do, don’t eat that shit. Can you eat your own? In minute quantities, surely. Obviously, we all do. We poop, we wipe, we touch ourselves, hey, it’s inevitable. We’re all still up and standing. Can you eat other people’s? Don’t even think about it. On the other hand, once again, I suppose we do, in very tiny quantities anyway, so small you can’t even see it. Wash your hands, dammit, wash your hands. You’re wondering about how you get traveller’s diarrhea on the road. You’re eating other people’s shit. Eating their E.coli and campylobacter. This is why intestinal parasites, typhoid, dysentery and cholera are so common in the 3rd world. The worms are in the shit, the shit goes into the soil, the soil goes into you. You can also get shigellosis, amoebiasis, and giardiasis this way. That shit is everywhere. Watch out for that shit. Don’t eat that shit! Don’t eat that shit!
