I had norovirus about 10 years ago and think it is the most seriously sick I've every been. 'I want to die' kind of sick.

I'm pretty sure I got it in a restaurant bathroom. Ever since then I've been extremely paranoid about bathroom germs, especially the ones where you have to touch things like the sink handle or door handle.

Norovirus is no joke. You can get dangerously dehydrated if you aren't careful.
