> It seems reasonable to suggest that masks reduce disease and save lives. This may be a scientifically provable fact. When masks are worn correctly by trained people as intended (form fitted N95s used for one short task in one room and then safely discarded), there seems to be a reasonable argument that masks are somewhat effective for reducing the spread of disease. But in the real world; the masks are the wrong types and aren't form-fitted, people are constantly adjusting them and moving them around and touching them, many people are basically walking around half the time with their nose hanging out, people wear them not only for many hours at a time but often for days/weeks at a time without being washed and breathing in their own moist bacteria colonies, etc. I'm not sure if real-world mask usage results in a significant net-positive: they could actually have a net-negative effect when you consider the amount of bacteria people are inhaling from their own mask.
