I don't think anyone is denying that.

If you are never exposed to germs in your life, when you do, your immune system will be overwhelmed by them and you will succumb to whatever it is and get sick. If you instead had a healthy immune system, it would fight off these germs and you would not get sick.

Like what The Enterer said, it's just about drawing lines. I won't drink out of the toilet, or wipe my ass with my hand, and then eat a sandwich. But I will eat stuff off the floor, and only wash my hands after I poop, or before preparing food.
