So tbis is an interesting discustion.
I would like to just talk about your point of ppl looking at you weird for wearing a mask.
Ill start with a ski analogy, when ppl started to wear helmets on sky slopes they got the look. I stopped skying for a while and when i dusted of my gear 2 year ago and attacked the slopes the good old fashion way with no helmet i got the look. So it about adaptation.
In canada when we see ppl with a mask pre covid was a sign that you where sick and contagious. So the reflex is that if tour not sick you dont wear one.
Another point is that Pre Covid, be honest when you saw ppl in certain asian countries wearing a mask all day long you have to admit that you tought is was peculiar
So to recap. Humans need time to adapt to new things in general. Some are faster then others. We see new things as odd, or are jugemental. Think electric cars!!
