Good Evening
I have a question, I do not have copd but I was a smoker for so many years that I am nervous the damage is already done. I have been smoke free for 3 years and walk 3 miles 5 - 7 times in a week. Is there anything I can do to prevent copd or the damage that may have been caused. I was very surprised that when I quit smoking I did not cough much. I am a retired 62 year old female. Thanks
