I am/was a smoker, who saw your site, took your breathing test and have quit smoking (at least for 2 days and counting). To be able to take a breathing test and see first hand what smoking has done to my breathing capacity was tangible evidence (specific to me, i.e. no way to say that won't happen to me) that smoking is taking my life.
So I am referring this site to people that I know that smoke.
Wonderful. I strongly suggest you also get our Breathing Improvement program to regain as much lung volume as possible that smoking has cost you. It will also help keep you away from smoking. Many smoke to relax and smoke to energize. Breathing properly gets the same results without the tar and nicotine. YOU be the BOSS.
