It was probably unfair of me to say such a thing. But do you wear the mask while walking alone outside and driving your car alone? If so why? You do realize that in this situation the masks are not meant to keep you safe from catching the virus? They are meant to keep you from spreading the virus by diffusing the cloud of germs coming out of your mouth you when you cough or sneeze.
If you want to protect yourself from breathing viral particles which are approximately 10 times smaller than the particles in cigarette smoke or absorbing them through your eyeballs... you need either a self contained breathing apparatus with a full face piece or at the least a respirator mask with a full face-piece and an appropriate filter. But since neither of those options filter the air being expelled from your lungs they do not meet CDC guidelines for this and do not help prevent you from spreading “covid-19”.
The masks are meant to reduce the cloud of viral particles emitted from you when you cough or sneeze they are not designed to keep you from catching anything. When you are driving your car alone, or walking around alone outside the only thing they accomplish is increasing the amount of CO2 you are breathing and reducing the amount of oxygen that is getting to your brain and other vital organs. With the “mortality conditions” that you have you probably need all the oxygen that you can get.
With regards to the “masks”. I wear an N100 respirator - not a mask, not a scarf. The PPE that I use is using a filter that blocks 99.95% of viruses (HEPA 13 rated filter). It forms a seal to my face (no beard or mustache). Do I wear it properly in the car, no. But it is on my neck ready to apply should the situation change rapidly and I find myself in close proximity to strangers.
I wear this because I have had pneumonia nine times, I have scars on my lungs, have had heart surgery, high blood pressure, etc. I will continue to self-isolate and wear PPE until I can obtain a vaccine.
