Why don't I ever get sick?

I don’t wash my hands all the time, unless I’m handling food. I don’t avoid sick people. I could care less if the guy at the deli doesn’t change his gloves before he puts my meat on the sandwich. He could do it with his bare hand, I wouldn’t care. I avoid “sanitizing” hand cleaners and soaps and stuff. I figure hot water and dish soap will do the trick. I’ll eat something that fell on the floor. If a piece of silverware has a spot of something on it that the dishwasher didn’t get off, I’ll use it anyway. I don’t care if someone takes a sip of my coke using my same straw (that would usually be the kids,) or takes something off my plate for themselves (ditto.)

Sounds like a recipe for SICK, right? But I can not remember the last time I got sick! About 5 years ago a UTI knocked me flat on my back for two days, until I could go to the doctor, but that had nothing to do with “germ” prevention.

People around me will be dropping like flies with the flu, or whatever, and I’ll come through untouched.

Why is that?
