That seems to work for some people!! Some of them even blame the Govt for everything even though they're not sick and have a 0.0001% chance of getting it.
Amusingly enough, OK, I'm not wearing a mask. Everyone else around me on the subway is. But there are people happily LEANING on the railings and crap, including with their heads. There are people TOUCHING the handles and railings and crap, then using the same hand to adjust their masks. Dude, seriously.
