I’m a big hand shaker (have to be, in my job), but you must train yourself not to unconsciously touch your face in the minutes or hours after a hand-shaking session, and make your way to a sink and soap to wash your hands as soon as you can do so in a socially acceptable manner.

In the era before cell phones, it was just as necessary to remind people not to put their mouths on a pay phone receiver (or any phone receiver). Those things were major disease vectors.

I worked for many years at a major hospital full of terribly diseased people, and never missed a day of work from a communicable disease, thanks, I believe, to the strict observance of these rules. (I am not by any means OCD. The hand-mouth rule is followed by many in the healthcare business.)

Idiots are continually comparing Donald Trump to Adolf Hitler, but the only thing I can see that the two have in common is a personal aversion to hand shaking. But really, you can shake all the hands you want and never get ill, if you don’t touch your face, and wash your hands at the earliest opportunity.
