Heather Spears was a runner who followed a healthy lifestyle of eating and exercising. Ten years ago, at the age of 33, she developed a case of bronchitis that just wouldn’t go away. Her doctor diagnosed asthma.

“It was weird,” she recalls. “My family has allergies, but no history of asthma. I was a fairly active individual – I ran half-marathons and generally took good care of myself. Now I am really prone to infections and my asthma is very difficult to treat. My doctor says, ‘Just stay home and try not to get sick.’”
