Do you wear a good mask. What kind of a mask do you wear. Whats the best

I don’t wear a mask. If I get sick I’ll stay home. I’ve heard doctors say that the reason they wear masks during surgery is to keep bacteria out of open wounds.....bacteria are much larger to catch through masks than viruses so they are effective for that. And doctors have also said never in the history of medicine have healthy patients without symptoms had to wear masks and take tests for contagious diseases.
