I saw nothing there that made me think anything was being accomplished by the masks. They're worn for sneezing and coughing. The masks do not protect you.
They keep you from spreading it as much.
They keep the viral load indoors, in places like the PO, lower.
Initial viral load is probably one of the big reason NYC’s numbers are as bad as they are compared with SoCal. Socal exposures are standing next to someone in the checkout aisle for 5 minutes. In NYC they’re sitting next to someone for 30 minutes on the metro north train in to GCS.
I wear one anyway because one of my daughters is listening to all the media scare crap and is freaked out. So, I wear it to make her a little less scared.
These liberals are evil. They are scaring people to death just to score points, or so they think.
Security theater. Not so much different from TSA. Makes plenty of jobs though.
