Well, you got hammered for this one, and even though quite often I find you over the top pessimistic, I'm right with you on this one.
Heck, I know my true behavior will drive almost any germ freak crazy and send them running if they knew, how rarely i wash my hands and how often handwashing for me is no soap, just the water. Even when I shower, I never scrub with a wash cloth. I get my hands soapy to wash the stinky sweaty parts of my body and shampoo the grease out of my hair (I'm cursed with an oily scalp). I rarely get sick, and my wife always complains that when I get sick, I never get as sick as she does or have it last as long. I once ate a potato chip I dropped on the floor of my friends car yesterday. Yes, I saw it and picked it up after it had been on the floor of a pick-up truck for >24 hours. Guess what, i didn't get sick.
You know, you might aswell save yourself the time and not bother washing your hands if you don't use soap. I'm not judging how disgusting that is or isn't. But it is basically a pointless waste of time to just pretend to wash your hands.
Also, friends car flooring has a 72hour rule. I just ate a couch Cheerio. Wonder how long that's been there.
