You would think there would be some research out there on the efficacy of masking, vaccines, and lockdowns.
There is research...it just doesn’t exist in the US. Around March of 2020, I remember watching German TV and a virus expert (PhD medical guy) got onto the subject. He cited various studies that masks in a highly infectious situation are necessary, but you’d to toss them every couple of hours. More humidity, less effective...was another thing cited.
But even after that, the Germans still went to the extreme on masks....even mandating them in outdoor shopping districts or fruit-markets as you were walking around.
During the former Covid insanity
Autopsy results was turning up evidence of mask fragments in lungs
Fibers of blue and bits of plastic from masks
Usually from low cost "made in China" masks
Better get to Home Depot and purchase some USA made 3M masks....go to the paint department for protective clothing for painters.
3M N95 Particulate Respirator 8511
Has exhaust valve to ease breathing and prevent build up of CO2 in the mask.
