Interesting article and really enjoy (as always) the images! In my years living in Hong Kong before the pandemic (but after SARS), there was a ton of mask wearing already, albeit only the surgical mask variety. Sadly, a lot of my students were pushed off to school by parents with a mask when they really should have stayed in bed! But there were benefits: I remember wearing them at several doctor's offices, no doubt helping me avoid illness well before I understood the use on a COVID pandemic level.
I still see wearing masks while driving alone in a car...

masks shed 4000 microns per month. 4000.
we tolerated smoking, second hand smoke, and pollution for generations; nary a mask in sight.
