Face Masks and Breathing

[Ray]

Good to know you are out and about. I simply meant that with your background, I suspected that by the time we met you would have read everything available on this subject amd asked a lot of guys smarter than I about what to do.

I wanted to add that some of the tests have demonstrated that masks similar to Debbie's are as effective as the 95% bacterial filtration efficiency, surgical masks.
