Someday in the not-too-distant future, many of us will startle our grandchildren by telling them that once upon a time, friends would meet for lunch, shake hands, and then eat without washing those hands after the shake. They'll be amazed that in the past, some people were insulted if someone didn't want to shake hands with them. We'll shock those grandkids by telling them that there was a time when folks would go to cocktail parties, meet new people and shake their hands without secretly thinking, "How am I going to sneak off to the bathroom to wash my hands before they serve the finger food?"
There's no doubt about it. Very soon, the handshake will be a thing of the past. It will go the way of the dinosaur, the lamplighter, and customer service. I will miss it. I already do.
The Center for Disease Control says that good hand hygiene is the best way to prevent colds from spreading. I place the beginning of major handshaking avoidance with the Swine Flu Panic of 2009. That's when hands officially went from mere appendages to virulent petri dishes. That's when we were encouraged to keep our hand hygiene up to par. That's also when the handshake started to disappear.
There's some faulty logic there. Just because the best way to stop germs from spreading is by having clean hands doesn't mean that the best way to avoid germs is to avoid handshakes. No, the best way is for everybody to have clean hands. Your reluctance to shake your friends' hands before eating lunch presumes they don't wash their hands when they should. What kind of friends are you hanging out with anyway?
