Also, I'd be interested to hear from anybody with the knowledge what the norm is for mask-wearing in places like Japan, China etc. I mean, pre-COVID, and not the mask-wearing to combat airborne pollution. Like, is it seasonal? Is it only in certain cities, or certain environments (public transport etc)? I can see some adoption of this in the US, at least for a while. Really looking forward to the childish, macho culture wars around it too.
