I wonder if this person knows how to wear their mask(s) correctly. I don't just mean wearing it, but proper medical protocols for handling PPE. And are there even any pre-2020 protocols for proper double or triple mask use? When has this been used in medicine in the past?

These people sound so sure of themselves in telling others how to practice medical advice, but how many of them actually have any experience or reliable knowledge in what they are saying? And I wonder the same about some of what our bureaucrats are parroting.
