I recently had a followup PFT and my FEV1 has gone down about 25-30% from 41 to 29 over the last year and a half or so. I know I'm probably at risk as far as catching flu or other diseases that might cause exacerbations and make my condition far worse as a result. My question is would it be good for me to stay out of crowds? I'm retired and usually avoid crowds but I go to a bowling alley/pool room where billiards teams compete in a league. It's fun and is a non-smoking venue but lots of people are there who might spread colds and flu, etc. I actually find myself somewhat sob at the matches sometimes as well. My question is would I be better off quitting the pool league to avoid infections? I've played for 4 years and like my team and opponents, but I would rather live a longer life. Any opinions would be welcome.
