First, the cat in the mask picture. No, I repeat, no self-respecting cat would submit to this sort of stupidity. 🙀

Thanks however. None of it surprises me. I am admin at Doc office. I am required to say “wear a mask” when assisting a patient. It sticks in my throat. Today more than ever. Not unique unfortunately is the comment I got back this morning: “I’m glad your office is still masking”. I HAVE taken to having fun with my phrasing in response “My doctors BELIEVE in masks.”. I sincerely say that almost every time. Two of my docs even look really smug in their high class expensive versions. Hmmmm.

I have long guessed at CO2 levels but have not had the documentation. Thanks for posting.
