But, I’m not infected.
I have a strong immune system, and I have not been sick at all in several years.
No cough, no sniffles... nothing.
It comes down to this... I’m not going to live my life assuming I’m infected with some sort of a disease, and I will not be wearing a mask just to mollify other people.
Each individual’s baseline health and risk tolerance is different, so each individual should protect themselves from diseases as they feel is appropriate.
