Also, people, germs are fucking everywhere. I wash my hands with soap when (if) I shit on them. But I avoid it otherwise because I want my immune system and gut flora to stay strong and the best way to ensure that is to allow a constant and natural exposure to a moderate level of naturally occurring bacteria.
I mean OP is still gross but focusing on that is what creates hysteria and/or panic which supresses the thyroid and weakens the immune system, allowing invasion. Better off to bolster one's confidence in your own immunity whenever possible.
TL;DR? : Be still, and know that you are the germ-whisperer.
