I think I mentioned in one of these posts that "chronic lung disease, such as bronchiectasis" is listed as a risk factor for covid infection. So, there's that: if I wasn't already/still being more covid cautious than most of the population, this would be an argument for increasing my masking etc. As is, we were already in a situation where I and Adrian were almost the only two masked people at the pulmonologist's office. So there's that.
