Basically, since the 90s we've put a much much higher value on human life. I expect mask usage to extend far beyond covid and handshaking to cease being a cultural greeting.
The world is significantly colder this year. I can't be the only one that feels it.
I find adults smiling to be gaudy and disconcerting, ever since I was a child. My wife included, although I like most of her so it's ok. Children don't bother me though, as it seems sincere.
COVID-19 has become more infectious over the course of the pandemic, with a strain that results in higher viral loads becoming predominant: https://pubmed.ncbi.nlm.nih.gov/32697968/
It's hard to compare across countries. But mask-wearing Japan and South Korea have higher rates of flu and pneumonia deaths than the US/Canada/Europe: https://www.worldlifeexpectancy.com/cause-of-death/influenza...
As surgical masks are much less than 100% effective even in ideal conditions, let alone actual wear, it wouldn't be surprising if more usage of them would just be an evolutionary pressure for flu to have higher viral output. Quite similar to how widespread use of less than 100% effective anti-bacterial agents just results in bacteria evolving resistance, reducing the usefulness of those agents for the most vulnerable part of the population who need them most.
Possibly confounded by disparate population densities.

Bangladesh also has a slightly lower flu/pneumonia death rate than Japan, even though it has 3x the density (though Bangladesh has a somewhat lower life expectancy (72) than Japan (84); Belgium, Netherlands, and Israel are all fairly close (80+) to Japan).
I think they are just sting-proof suits.
2020: Surgical masks are a bit much to expect people to wear during a pandemic, Ebola has been circulating in Congo since 2014, and we'll need airtight space suits for a murder hornet outbreak.
Truly, the 90s were a simpler time.
