Recommend this book, anon. I posted it yesterday and have started reading it. Worthwhile and related to your post.
What I find ridiculous is that all they talk about is wearing the mask. No decon procedures. That cotton fabric is going to get moist from your breath. Then it will trap all manner of particles and you're just going to go home and pull it off, toss it on the counter, desk, etc? That really did a lot to protect you.
By 'you' I don't mean you, anon. Just in general.
