I wrote the above post in a hurry and didn't proof... of course, I did not mean "Do you think doctors and nurses – and I assure you, some of them even have asthma and heart conditions themselves – work for hours in surgery wearing masks and don't become ill?" I MEANT: "Do you think doctors and nurses – and I assure you, some of them even have asthma and heart conditions themselves – work for hours in surgery wearing masks and BECOME ill ?" Of course not - not from wearing masks.....My point is, docs and nurses do have to wear masks for far longer periods than does someone going to Walmart or the grocery store who whines and complains they can't breathe or are having some other made-up or imagined problem to back up their claims, stoked by propaganda and inaccurate online "medical" BS. Docs and nurses would have spoken out long, long ago if they were gasping for air, having arrhythmias, fainting from hypoxia and more from wearing masks. Folks, we are hitting 1000 Americans dead a day now from COVID-19. Again, stop the craziness and grow up - masks save lives. Countries that mandated mask wearing early on escaped the nightmare now in this country. Sure, masks are only one part of the equation but that matter- a lot.
