LOL...when I first saw the subject, I just if you are happy to have COPD then you must have really been worried that it was something worse.  From someone who used to have breathing difficulties, your environment may be contributing to your difficulty in breathing as well.  If you live in a large city or  near one then the pollution there may also be contributing.  Taking vacations away from the city will help in giving  your lungs a break.   My doctors where thinking that I might have COPD but in reality it was just that my problems were because I lived in a highly polluted area between 2 big city's.  I no longer live in that area and I went from using an inhaler at least twice a week to not using it at all.

Enjoy your happiness, get some fresh air, and stay active if possible.  Keep those lungs strong.  And congrats with not having cancer.
