Simple rule that I follow: I think, "What would the virus want me to do in this situation?" Then I do the opposite.
there’s no actual evidence that the virus is spread in such a manner. There was one theoretical paper that suggested that it
might be, but it was all based on computer simulations. However, it had nice colorful graphics, so the media glommed onto it and it suddenly became gospel.
