The media touts the Asian, “mask culture” as being wiser and safer than the US carefree way of life, but I remember that in February of last year the Japanese were having a big flu outbreak. I would like to see an analysis of mask usage and I would bet it makes little difference.
If sick people stayed home for 3 days you'd see a huge difference. The problem is, especially millennials never stay home sick, they're out to bars, off to work, couching and sneezing and touching all the while.
