You are correct they don’t seem to go together at all. I asked my doctor about this and he showed me my test results that very clearly showed that I have asthma. Without an inhaler my lung function is somewhere just below 70% it’s capacity where someone without asthma would have 100%. He could not give me a good answer to why I can run so fast but guessed it could be because of the great amount of aerobic training that I had been doing for a couple years before I developed asthma
