OK. I'm gonna catch heat here for this, but I have a doctor that is more concerned with whether I have had a flu shot than what is wrong with my knees. I'm pretty sure that it is arthritis, but my doctor didn't even check my knees at all.
So, don't give me this crud about experts.
Secondly, I do "occasionally" wear a mask, but ONLY because someone absolutely requires it to enter their premises. Otherwise, I have a concern of oxygen deprivation that a mask would contribute to, so when I get inside said premises, the mask comes down below my nose. I'm not sure I can be convinced that when one exhales that ALL of the carbon dioxide escapes through the mask, thus when in inhale, I'm taking in some carbon dioxide with the oxygen. Thus, I'm being deprived of some oxygen.
