What does a mask do? Blocks respiratory droplets coming from your mouth and throat.
Two simple demos:
First, I sneezed, sang, talked & coughed toward an agar culture plate with or without a mask. Bacteria colonies show where droplets landed. A mask blocks virtually all of them.
Tempted to boycott Facebook 🙃 I can report something which has resulted in people showing up at a given address and nearly killing a person, but it not being seen as against ‘community standards’, yet me saying a comment is ‘ill-educated’ is bullying and harassment 🧐
