Thankyou for all who answered my last post. Very helpful
Now this is easy. Last June 2016 Lung capacity 50%. December 2016
45%. Today 39%. I do not drink and I do not smoke [since March 2016], I go for long walks, but this year, I keep getting cold after cold. Is there any suggestions as to how to increase my lung capacity, if only a little bit. Very depressed tonight
