Not necessarily a good sign of health if you have trouble breathing through a face mask.
To be fair, masks are terrible for one’s health. In his case, his brain cells are too busy trying to keep him uptight, there’s not enough left over to remind him to breath.
They cause issues with millions of people. Not to mention they’re obnoxious and unnecessary. Btw, most anything you cover your mouth and nose with will limit your oxygen intake to one degree or another.
