A couple of days ago I came across the idea that, instead of greeting people by shaking hands, these days we should bump fists. That struck me as a cool idea, especially if Coronavirus is spread through touch, but how about going a step further and just doing a Vulcan salute to one another? Leaving aside the fact that I personally struggle to get my fingers into that position, it seems to me that that would be a very civilised way to greet each other, especially since it is synonymous with wishing one another ”Live Long and Prosper..” There is no touching involved at all. Mind you, Leonard Nimoy apparently borrowed the gesture from an orthodox jewish ceremony, so it might have hidden religious connotations.
Either way, the least we can do to protect one another is sung about here (nsfw)
