One has to wonder why they’re so adamantly lying about that. Masks will harm you a lot, especially with high usage. Why are they pushing so hard?
An older pharmacist friend, at the height of the mask mania, sent me a photo of surgeons operating over a patient, with a heading along the lines of “masks work”. I replied that if I had to stand over the steaming innards of somebody’s disease riddled torso I’d want to wear a mask too. Grocery shopping or working out in the gym, not so much. He has since come around to sanity, BTW.
