I feel a little let down and misled after Fauci admitted the 6ft rule probably didn’t have scientific basis

That recommendation came from the CDC. I recall seeing some ANSYS fluent modeling of particulates from coughs and sneezes in confined spaces. That showed how wearing masks would be beneficial. It all came down to reducing the load we received. Cigarette smoke particles can hold hundreds of covid viruses on each one so if you could smell the smoke, the mask was pretty much worthless. When we had no immunity at all, just a few viruses were all it took. There were some papers out there suggesting that people with Neanderthal DNA possibly had more resistance to corona viruses but since this one was a weaponize strain that probably didn’t help. I participated in the testing of one of the immunizations and was so happy when my blood test indicated i had immunity!!
