If you’re susceptible to upper respiratory infections, do you really think it’s a good idea to wear a petri dish right over your face and nose?
You are the one calling a mask a petri dish not me. A petri dish is Walmart, Costco, the grocery store, the doctors office etc. Wearing a mask in any of those scenarios is in my opinion not a Bad idea. But I’m not trying to talk you into it. As I have previously stated I think the surgical masks afford some degree of protection.
