I’d love to see a sample from a surgeons lungs they wear surgical masks every day during every procedure they do and have for 25+ years. They are called surgical masks for a reason. Same for dentists they wear masks every exam, every procedure and every cleaning by law for both types of professionals. Since we don’t have surgeons falling over dead nor dentists one has to wonder what the actual effects are.
I doubt our medical personal have been using the low grade MADE IN CHINA masks the public received. EVERY package of masks I checked in stores was from China, and I previously posted a recall notice from Canada pulling those masks off the market because they contained chemicals (graphene oxide) which cause lung damage.
