Fully vaccinated or not, many workers are still required to wear a mask in the workplace. We can do a small thing to signal our solidarity with other workers, even if they don’t recognize it.
I tried going without a mask at Costco today but felt crappy when I looked around and all the workers still are required to wear them. I felt better and more connected to my fellow workers once I put it back on.
I dunno, it's hard to find accurate stats. They say Pfizer's is 95% effective against preventing illness, can't find anything on death tho. But whatever it is, wearing a mask cuts my chance of infection by 65%, so if the reduction in death rate is the same as illness, that drops my chance of dying from 5% to 1.75% and that seems like a pretty good tradeoff to me for the two seconds it takes to slap a piece of fabric on my gob.
