Do you believe in germ theory?
Germ theory as in you ingest a germ, so you get sick. Rather than terrain theory where you’re infected by a germ, but it won’t proliferate if you’re healthy and you don’t get sick.
It’s a very interesting theory and lately I’ve come upon people who purposefully drink or eat the most rotten and gross food and water to try and disprove this theory. Like rotten raw liver, still water from hot ponds, etc.
Not to mention dogs which do this for fun, mine buries raw chicken legs and comes back to them a few days later, she’ll lick my face as a greeting so you’d think I’d get sick (or at least the dog will).
