Yup, that's a good one. Wonder how the "WHO" would explain this one even when they said, "If you are healthy you should not be wearing one". *Chinka imposed their people wearing them way back when *sars1 occured and for way too long. I started questioning why in the heck would they? Then fall2019 I saw one wearing one near my home while riding a BYCICLE!!! I said, to myself, "Oh hell no, NOT here you don't"! Look what's happening now! Unbelievable.
