1/Here's a very sane look at masks from a very sane virologist @chrisvcsefalvay https://www.city-journal.org/reality-of-wearing-masks

"As states begin to reopen and America tries to recreate normalcy, masks have replaced social distancing as the new moral statement... As a virologist, I find this perplexing"

2/ "More than anything, the scientific rationale behind masks appears to be that wearing them does little harm... The viral particles that spread Covid-19 are tiny bundles of proteins and nucleic acids, about 0.1 micron in size—or one hundred-thousandth of a centimeter. "

3/ "Clearly, reducing the speed and pressure of droplets from sneezing or coughing that spread infections, as those of the coronavirus responsible for Covid-19 do, is likely to have some effect, but how much remains to be seen."

4/ "Yet the evidence is hardly strong enough to elevate mask-wearing into the epitome of moral behavior. Doing so reflects a greater preoccupation with the psychological effect of masks—perhaps as a restoration of control in the face of an unseen and often perplexing enemy..."

5/ Go read the whole thing... the last paragraph is very profound. https://www.city-journal.org/reality-of-wearing-masks
