Al, I have alot of respect for you.
But, I have sense enough to know when I feel bad and would stay away from others if I did. Others don't have to worry about me giving them a dose.
The mask is to retard the aerosol spread of the virus particles from mucous and saliva into the air. And retard the aerosol spread from and infected person to others, to some extent. Most maskers don't wear one that really prevents the spread. Its only enough to make them feel correct.
Social distance and cleanliness will take care of the rest. If you are sick and feel bad, stay at home and away from others. Don't put on a mask and go out into the world and think all is fine.
I am an essential personnel that has been dealing with the public on a face to face basis since day one, bareback. I use distance and wash my hands often, avoid sick looking individuals. I will shake your hand if eye contact allows me to.
I am not in the group that is really risky of the worst of cases, but I don't want it. Or any bug going thru the public.
I am in no way condoning risky interaction between others, just use the brain and science. Real science, not the Facebook kind.
