If there is a super deadly virus out there making people drop dead, what the fuck is a mask going to to stop it?
As for not spreading it to other people - let me think, here's an idea for people, cough and sneeze into your sleeve, that's actually advice doctors have given for many years.
I have to wear one when I go into the office (Fed Work), but otherwise screw that, I believe in herd immunity. Of course in my case it's more like heard immunity. If I don't get exposed, I heard I am going to get week and die from it. Honestly, I believe like millions of Americans that it was here last September-October, was exactly an attack by the PRC and they then released it in Wuhan 3-4 months later to make it look like an accident. It was an engineered act if war. No doubt in my mind and I know people in the medical community who believe the same thing.
