You just prove that people can pursue their dreams and that we can overcome our limits. Nobody can tell us "you,can't do this, you can't do that", only ourselves know ourselves best.
Your situation is quite similar with my nephew, he was also asthmatic but he loves sports, now he has joined JKA(Karate) and his health is improving. Thanks for sharing :)
