It's not only a way to gauge subservience and train people, it's also a way to give them brain damage. Do you know what an N95 worn for 8 hours can do? Even the cloth ones are bad news. The good thing is even though I see people masked, I see mostly the cheap throwaway ones, that (I hope) most people understand do nothing, but they're just complying. Now if we can just get them to stop doing even that.
