@Pat Yeah I think there isn't much doubt about that; you wear it right you're hugely protected. (Haven't healthcare workers been using these for years when doing flu swabs so when they get sneezed on by sick people they don't get sick?)
My question about your photo is, do you really need masks outside? I hear you can't really catch covid outdoors in normal situations.
I could see putting one on before I go inside a public space. But, for me, I feel like the risk is down to "background levels", time to move on. I'm not going to wear a mask for the rest of my life.
@Pat the 24 ft guy – but how do we know he didn't get it from someone else, say, in the bathroom? Was it one of those silly pseudo "outdoor" tent things restaurants had, as if it was sheetrock that caused covid?
Anyway: sure, it's possible, I'm sure like a couple people got sick that way.
@ech
Early in the pandemic there was a case of someone who became infected at an outdoor cafe who was sitting 24 ft. from the guy who infected them.
There are a lot of variables outdoors -- notably air currents and UV. At night when the air is still the virus will survive outdoors.
My rule of thumb is that if anyone around you was smoking would you be able to smell the smoke? If yes then wear the respirator. Chem odors from smoke will transmit more readily than the virus, so this should provide a margin of safety.

Depends on how long you live.
