All masks do is slow the spread......
Well. well....... you get it.
The point is to retard the spread
Most people don’t properly handle the masks especially with disposal
do they wear gloves do they change out the masks several times a day?
I see masks in parking lots, in ditches, and everywhere else with no concern for hazmat to pick up these used virus laden pieces of plastic.
Even THAT isn't proven. Sure, surgeons wear them. That's because when they cut into a patient, that patient gets .... well, JUICY, as Ann Barnhardt once said on her site. Meaning that blood and other body fluids tend to squirt out. SUrgeon can't risk that stuff spurting into his face.
