I just read a very good piece by my friend Courtney, aka “godless_mom” on the efficacy of mask wearing during this pandemic. She makes, as usual very good points and of course, cites data where it’s required to show that masks do help slow the spread of the virus. As I go through the days, I read various essays, even some purported “scientific” papers on the usefulness or not, of masks. There’s a lot of opinion out there and most of it is based on very little science.
