Odd you mention that.
A controlled study showed that masks in the operating room actually INCREASED infection rates. The reason was the masks rubbed the face as the surgeon talked and flakes of skin from his face fell into the wound.
You actually make a point about face coverings being ineffective. And science shows it.
