I have been prescribed a succession of inhalers since 1992 when, at the age of 52, my shortness of breath during exercise was diagnosed as due to asthma. I've had blue, brown, purple inhalers but until the latest one, a shocking pink colour, I was resigned to further curtailment of my mountain biking activities. However, with the new bronchiodilator, I have now resumed biking over the Brecon Beacons, doing 46 miles down the Taff Trail from Brecon to Cardiff only last week. My score on my PulmoLife tester has risen from high 40s to mid 60s. Now, is it the inhaler that has effected this improvement, or it just that the renewed lung exercise during strenuous activity has brought it about? Any ideas?
