well, I was thinking more of the sharing hands and contact aspect of the whole event. If everyone were washing their hands, it wouldn’t really create the human chain that they were going for…. but if everyone was washing other people’s hands, you could keep it clean and still have human contact across the country.
Funny how people are scared of shaking or holding hands these days…
