I didn't stop wearing 3M FFP3 masks, which I buy from a UK online store. No covid, no flu, no RSV. Yes, I don't wear them like the dumbos who remove them at the airplane to eat or who believe covid somehow disappears outside even when you have somebody right in your face bombarding you with their spit and aerosols. Yes, tell me about it - it requires some solid discipline, but covid is no flu! We're just 3 years into it and he have piles of data or the accumulating damage for each incident - brain, endothelium, kidneys, myocardium - just for the quick to spot victims of covid so far! The mitochondrial damage could lead to tons more - it just takes time and lots of accumulation. Even being super strict, we still got it in our household when somebody broke the rules. Every time we wore masks like smart people, we were fine even though we were around sick people, in airplanes full of sick coughing and sneezing people. Masks do work. They require behavior modifications, but isn't health the most precious thing?
The worst thing is that we don't make a dent when everybody want to live their (shorter) lives without doing the necessary to prevent mutation. This is the most contagious virus known to science now and each new variant becomes better. Okay, it's mortality is less, but isn't it because we all got immune? Just pray this doesn't suddenly reinvent the mortality of SARS or MERS - they it will be the end of the human civilization as we proved we're stupid and self-entitled!
