Something ridiculous about photos like this. Performative mask-wearing? I’m assuming this basic mask is not that useful and you need an N95 or similar?

Useful but only for keeping hands away from face. Via Virologist who said that N95/100 were more useful as masks. Wonder what more useful means, though?

He said surgical masks were problematic because of moisture within 15 min of use. I didn't think of that. Wondered if 95s had a moisture expiration time
