Yes.Well I think that years of intense cardio had a lot more to do with it than vaping.
Keeping your heart rate up and huffing and puffing for 30 minutes to 2 hours non stop causes your heart and lungs to become stronger over time. There is an area in the bottom of your lungs that never gets ventilated with normal breathing. The only time that it does get ventilated is when you become out of breath (or doing breathing exercises). This is the same area where COPD related lung conditions start.
I think vaping helps to reduce the damage to the heart and lungs, but the cardio exercise is what strengthens them. I'm not a doctor but I was a fitness instructor when I was in the army back in the 1980's, and that gave me the knowledge I needed to get back in shape.
I wasnt implying tha vaping cured COPD. More that the over diagnosis of COPD is a known phenomena. People who have been given what they thought was a life sentence with emphysema have found that by quitting cigs and recovering some fitness level the diagnosis of emphysema turned out to be incorrect.
What I found to be interesting about it was that the increase in diagnosed cases of COPD coincided with other events in the legal and money markets.
Im sorry, I didnt mean to side track the thread away from its original intent. Inspiring stuff!
