We don't have much control over events in the world but we do have control over our own behavior and actions. Stop the mask insanity and stop wearing masks! The vast majority of people in the world have a medical condition which precludes them from wearing a mask. It's called being healthy! If it's makes you feel better to have a doctor's exemption then with the power invested in me as a Pede I hereby declare that you are all Pede doctors specializing in your own health. Go right ahead and write yourself a note exempting yourself from wearing a mask. Should you feel the need to produce for some busybody you'll have it ready.
