Re: Which Players Suffer From Asthma?
There is a condition known as 'exercised induced asthma' that tends to be more prevalent in athletes than non-athletes, particularly those who have higher aerobic activity incorporated in their exercise. Something like 1 in 15 Olympic athletes suffer from it. It's treatable, particularly compared to the more generic form of asthma (the one you stereotype with the wimpy kid in P.E.).
For example, Jackie Joyner-Kersee had asthma, and she was clearly one of the greatest female athlete's of her era. A lot of distance runners and cross-country skiers have the exercise-induced variety, which (I gather) relates to your lungs being used beyond their limits.
