That said, I've been pretty good about hand washing and avoiding people my whole life. Having grown up in a medical family, personal hygiene was not something completely foreign to me. As a result, haven't had a history of being sick regularly, but it still could/would happen from time to time.

It was after I stopped eating out that I completely stopped getting sick. I am not exaggerating when I say that in the last 6 years, I have been sick 0 times. That correlates perfectly with me stopping eating out. Correlation != causation, I know.
