I had stopped wearing the mask, but seeing the numbers starting to tick up, I'll start again.
I had reached a point where I wanted to wear a mask if I felt I had symptoms of anything, to keep it to myself. I think there is some data that masking also helps the wearer stay healthy, and that is why the phrase is something like "the wearing of masks slows the spread..." - that is certain - rather that who is getting the protection...the wearer, or the other person's in the wearer's presence.
I really liked feeling like I did not need to wear a mask this summer. But, that's a little naive and selfish of me to stop there with that momentary joy, and not go further to consider what is the best practice for my well-being (and the well-being of others is part of my own well-being) in the long run.
We'll see how it shakes out, but I'll be carrying one for situations where it is crowded, or the ventilation is bad, or when numbers are up.
