Right now, I have three reasons to wear a mask:
First, getting COVID would be a nightmare while I am desperately seeking housing, and while I am in a place with no kitchen or bathroom to myself if I need to isolate. I would rapidly go crazy if fully confined to my hot, muggy, awkward temporary bedroom.
Second, the wildfire smoke ebbs between visibly hazy and not very perceptible, but the PM2.5 and other components are awful for your lungs whether you can perceive them or not.
Third, I have vulnerable relatives with pre-existing conditions which could make COVID very serious for them.
