I've recently picked up better hand washing after that first surgery this year, and beefed it up more after someone I know who's a nurse told me it could have contributed to my bad kidneys. I don't know how true that last bit is but is doesn't sound outlandish.
It's a shame this is what it took for me to finally get it together. I hate to admit this....but before all this the only times I washed my hands in a public restroom was when there was someone else in there. Being paranoid by nature I always assume all people are like the OP and will automatically notice/judge me for not doing it.

I have a daughter who is almost obsessive about washing EVERYTHING and I'm always pointing out that the air we ALL breathe contains particles of -
DOG POO !!!!
BIRD POO
HUMAN POO
COW POO
HORSE POO
VOMIT PARTICLES left on the street by the saturday night drunks.

The stuff on our hands is minor compared to what we breath every day of our lives.
