Lol, OK. Whatever you wanna think. And I never mentioned the word "custom".
And if someone asked me right before I jumped into a freezing lake if I wanted to go naked or wear a t-shirt, I'd take the shirt. For all the good it would do me...
Okay, you think my example was funny.... Wait another two or three weeks when this deal explodes in this country and walking into any grocery store (for example) will be esentially the same as "walking into a room full of infected people".
There are many videos on the internet of doctors and other medical professionals telling everyone that masks absolutely do help prevent infection. In fact, several of them have said it's almost criminal that the government has told people not to wear them.
You're free to come to your own conclusion, as am I.
