Greetings Improved

In these days of a new highly contagious respiratory virus, greetings like hand shaking, kissing, and hugging have become transmission vectors for disease. We will determine a new way of greeting that doesn't involve physical touch. Based on some of what I've recently discovered, that probably should have happened long ago. I've only recently found out that many people do not wash their hands when we expect they would (or should). "We want to go to the movies and sit down in restaurants and yell expletives at football players in packed stadiums and hug friends and decide to not wash our hands after using public restrooms because that's what we've long done" (emphasis added) -- an aside thrown into a piece about eating meat. A BBC piece may enlighten you as much as it did me. I was really surprised (and grossed out). And no, I'm not talking about people in areas that lack basic "facilities" either. 

How did handshaking come about, anyway? I'd heard handshaking was to show you were not carrying a weapon. (IDK how that would work for left-handers, but there are fewer of them.) "The history of the handshake dates back to the 5th century B.C. in Greece. It was a symbol of peace, showing that neither person was carrying a weapon. ... Some say that the shaking gesture of the handshake started in Medieval Europe. Knights would shake the hand of others in an attempt to shake loose any hidden weapons." from Wikipedia

In some cultures, handshaking is not the standard greeting. Some greetings from around the world are here.  Below are some options, maybe? Or, maybe not. 

          1.  Fist bump - still requires physical touch, leaves a lot of opinion room for "how hard?", and... what about rings? Would a decorative ring to a bare fist hurt? I wear several finger rings, some with stones, on both hands.

          2.  Asian bow - as long as it doesn't devolve into some kind of "who bows lowest" having some hierarchical meaning, this seems ok, but the arms stiffly at your sides seems awkward. Maybe just a little nod and/or slight bend?

          3.  Namaste - a small bow, hands palm to palm held about chest level seems kinda, maybe an option, with or without uttering the word (how *do* you say it, anyway? na-mus-STA is my effort). Then again, there's this outlook.

          4.  The elbow bump - before we were all wearing masks, weren't you told to sneeze into your elbow? I don't think I like touching elbows with someone else... 

          5.  The foot or ankle tap - requires balance for starters. Flailing arms or hold each others' hands for balance? Looks like some weird start to hokey-pokey, or maybe a square dance intro(?). Don't you need to be fairly close to pull this maneuver off, too? No. Just No.

What do you think? I'm kinda in favor of Live Long & Prosper, with or without the words. Or maybe Greetings & Salutations could be modified a bit to add distance (and because it looks ridiculous that way, LOL).
