My problem is that my asthma was badly controlled when I was a child. I was born with it and diagnosed at 18 months, but it wasn't really properly under control until I was in my teens. It resulted in permanent damage to my lungs, so it doesn't matter how well it's controlled now, my lungs will never be as good as they could have been. It's something I just have to live with. It doesn't feel like a hardship because I've never known any different, but it must be amazing to have lungs like some of you guys.
