Not at all. I have the immune system of a god and rarely get contagious diseases (never had the flu, had the stomach flu maybe twice, and strep throat about 3 times...and minor colds. That's it). Like I'm almost never out of school for illnesses besides migraines. So I don't care much about germs at all. I'll drink other people's drinks if they aren't sick and don't care about touching doorknobs or other people's hands or handrails or much of anything.
