So today I went to the doctor (for something un-running related) and the doc brought up the fact that I have asthma. He asked me if it bothers me and I said that I have started running and haven't needed my inhaler once. So with that, his eyes lit up and he asked me if I had needed it in the last couple of years. I replied no and voila! He 'declassified' my asthma, meaning now I do not have it!
He said it was the combination of cleaner air (I live in the countryside now), and getting aerobic exercise! Woohoo!
