Have you tried wearing an n95 mask while doing anything more strenuous than walking? I have no health issues at all and I can find it difficult to breathe. I don’t think obligating (legally or socially) people to wear n95 masks is realistic. Unfortunately, just like many socially charged issues in 2023 it just takes some common sense. I’m not implying you’re lacking, just my .02.
I mean I couldn’t really tell you whether kimchi is expired, covid or no.
