May 29. Kevin Kelly declares that from now on he will refrain from shaking hands. This is a good test, because I really don’t care about shaking hands, I don’t benefit from it, and I wouldn’t care one bit if it vanished from one day to the next. And yet I think it’s wrong to abandon it, wrong in relation to the risk it poses. Might as well wear a bicycle helmet then. Or touch the poles in the subway only with gloves. I have an immune system for that, a top notch New York City immune system. Others may not have one and behave differently. But I think it is more important for us to improve our bodies so they can handle the world better, rather than to hide from it.
