Masks do more to protect others than they do you. Which is why we are safest when everyone wears a mask.

When the checkout queue is moving slowly, some people try to move the queue forward by moving closer tho the person in front, even though the queue hasn't moved. I've noticed that people who do this are always maskless.
My local store is near a homeless shelter; homeless people face much greater threats than what amounts to a nasty respiratory virus. But I like social distancing; it tends to improve my sense of having personal space, as well as making me feel safer.
So I have to accept there's a way of thinking that makes it actually wrong to mask-up.
Incidentally, I walked off the street into a pub the other day, for a straight whisky at the bar - I didn't plan to hang around (nobody was masked, of course, because you can't drink through a mask). Well I was basically called out by this grumpy fella, because I came in masked. I mean, he was joking, but he obviously despised me.

> Disposable medical masks (also known as surgical masks) are loose-fitting devices that were designed to be worn by medical personnel to protect accidental contamination of patient wounds, and to protect the wearer against splashes or sprays of bodily fluids (36). There is limited evidence for their effectiveness in preventing influenza virus transmission either when worn by the infected person for source control or when worn by uninfected persons to reduce exposure. Our systematic review found no significant effect of face masks on transmission of laboratory-confirmed influenza.
