Colleen, how kind of you to ask! He is in the hospital right now, having had dizziness etc. Negative for covid or flu, so they are doing many tests now to see what is causing his symptoms. They are going to do a lung scan today to see how bad the scarring is. He does not seem to be low on oxygen as yet, but is somewhat breathless. Thank you again for asking. I would say you are a really good moderator!
