I suffered from severe bronchial asthma throughout my early years and up to the age of 18, when I left home for university. It was eventually discovered that I had an acute allergy to cats, of which we had 3!

Over the years, I am now 72, I've had breathing difficulty of varying degrees, but since moving to FL 13 years ago I've felt better than I have since I was 4. I use Albuterol as required, but before a ride, I use this
