If we were that susceptible to germs on our bodies, we'd never have survived. Unless one has a compromised immune system, our bodies are perfectly capable of fighting off and destroying most germs. If that wasn't the case, parents would croak when their kids turned three.
If one has a cut on their hand, then it's important to keep it clean, as you've opened the door, so to speak, for bacteria to enter and cause infection.
How many people do you know who've had to have limbs amputated due to infection? Go on antibiotics for no reason other than a cut on their hands? We are not fragile little creatures. Our bodies are powerhouses ready to defend against all comers....'ceptin' a few.
I just love the sanitizer cloths they have at most supermarkets now. As if we are going to catch some awful disease from touching shopping cart handles. Because, you know, before they had those, we were catching deadly diseases by the score. Why, they were droppin' in the parking lots.
Tell your lovely wifey to buy stock in Procter & Gamble. And if you ever call her "my idiot wife" again, I'll fly through your computer screen and GIVE you something to wash your hands about!!!!
