Yeah. A few years ago in a health class in high school, I was told that if you use like anti-bacterial soaps or hand sanitizers, eventually bacteria will get used to it and those products will stop being effective. Thinking about it, though, it doesn't make a heck of a lot of sense because it's not like it's the same bacteria individuals on your hands day in and day out.

I probably won't be getting the flu shot. Shots fascinate me.
