I realized a great way to try to wake these people up. I saw a worker at a grocery store today, so I said to him, "So they are still making you wear a mask?" (of course, knowing it wasn't required because most, if not all of the other employees don't wear masks), then he said, "No, I just want to", so then I said, "You really should look into the information about masks". That's all. It's now up to him, but the thought should now be in his head, and maybe he'll actually look into it. Of course, my ultimate action will be to wear a T-shirt that says, "Wearing a mask in public is like carrying a sign that says I'M AN IDIOT! " :)

Yes! I like that "Petri dish" analogy. It is so correct. Even OSHA in their long-held guidelines (until 'COVID") stated that N95 masks (respirators) were to be used as a last resort in environments of high airborne particulates and not to be used for more than 20 minutes, to which they were considered as useless. N95 respirators were originally designed by 3M Corporation for use in the coal industry. They were never designed for the prevention of germs. A variation of the N95 is the surgical mask, which really has the same functionality as a N95 with perhaps some aesthetic variations. It is designed so the surgeon doesn't drool, cough, or sneeze into open wounds. It has more to do with sputum than air born germs.
I can tell you that some surgeons sweat that sometimes drips into the open surgical field.
Yes, this is a possibility. You must be alluding to field surgeons or inept surgeons under review. Hospitals are temperature and atmosphere controlled.
it can still get warm and sweaty in the OR under those gowns and masks. Retired surgeon here.
Not sounding beneficial to the patient and sounds more like a M.A.S. H. environment. This may be another example of hospitals not pursueing GMP as much as pursue profit. In the end who pays?....... Seems like the patient does in more ways than one can imagine.
