But this isn't what the sciencey people say. Trust me, they know what they're talking about. They paid a lot of money for their "degree" (what a choice of words, by the way...), so that means they're an authority on the subject.

I find it increasingly more difficult every day to understand the sheep mentality of people. If people would only spend a few minutes doing some research. A good place to start would be Respiratory Acidosis, Hypercapnia, and brain Hypoxia. These are all possible symptoms of mask wearing. Also the covid virus has been measured at between 80 and 140 nm. Wearing a mask to prevent the virus from being breathed in is equivalent to putting up a chain link fence to keep a mosquito out.
