Trump: The Radical Leftists want to take away your freedom!
Voters: Why? The doctors in your administration are already doing a bang-up job of that.
Masks have been quite common in Japan for decades.
Do they work? Keeping the aspirant spray down, yes they do but for inhalation purposes you need a respirator with a micro bio filter. And I’m not even sure that works against viral pathogens but when I see scientists working behind glass isolation booths in a negative pressure room with gloves and respirators on maybe it does but one would have to go to the extreme in order for it to be effective.
That said I prefer not to share my aspirants as I walk about a store. So I wear a mask. Until I get tested and I prefer not to unknowingly shed because I care not to share.
