CDC on how to break the mask rules in the best possible way

Reusing masks is okay.
Bandannas are okay.

BTW, you are perfectly correct in saying that distance works instead of a mask, and the generally accepted distance is 6 feet. There is some recent research on droplet vs aerosol vs airborne transmission, suggesting that it's more complicated , and other research suggesting that some patients are capable of forceful expulsion of droplets ( that would be a "cough', I believe) for greater distances for which I have no footnote. This is all pretty deep in the scientific weeds for me.
As an occasional victim of FDA and CDC investigations, it is absolutely stunning to see the normally righteously indignant technocrats say "well, screw it, reuse the disposables and make your own masks." It's a "Hold my beer, watch this!" at a really high level.
