Saturday, when I was back in the E.R., one of the patients was wearing a mask - but she only covered her mouth. Apparently, to her, covering the nose made it harder to breathe. She looked at me, I indicated that it should cover her nose, too. She did, for about five minutes.
In California, they said that if you don't have a mask, a bandana would also work. I have bandanas - but am fortunate to have a real mask.
Pellicle - we can count on you to come up with great maerials. The thing that you posted about masks should answer questions about masks that many of us probably have.
Thanks
