I know. I'm a big fan of handwashing and I do believe it helps immensely. Another tip is I do not, absolutely, do not, use public writing implements when at a doctor's office and they want you to sign in, or when I sign my receipt at the store. I carry my own. Once or twice I have forgotten or lost my pen and it was a huge production. I think these are notorious for spreading viruses, esp. during cold/flu season.
During the flu season I wash so frequently that some think I am neurotic.
Who cares what they think? I don't catch the flu every year like most folks.
Also, if you are ill, handwashing prevents you from spreading the joy around.
Back in the early '60s we had "health" classes in elementary schools. Handwashing was taught and praised.
Nowadays they teach kids how to put on a condom one-handed.
Sheesh!
