Most masks do nothing to prevent the transfers of the airborne virus. They might prevent globules from one but to prevent airborne virus is a joke.
The mask is simply a symbol. You are made to wear one to remind everyone that the panic must continue.
I see you read the daily reports that non medical folks post about the masks.
I wonder why they wear them in operating rooms? Must be so you dont sneeze into an open cavity.
And, if they are so ineffective how come places where the people wear them have lower rates of transmission?
I guess they are all wrong.
You have been the victim of normalcy bias. Use the brains God gave you. And if you want to go to Costco, wear a mask.
Honestly, I do not care what you do. I dont write that in a hateful way. I really dont care. Wear a mask or not. But understand that Costco will make you wear one when you go in. Dont bitch about it.
