Pack a day smoker for 30 years. Shorter of breath and one day closer to death. Someone showed me an e-Cig in 2010. December 20th 2010 I had my last cigarette. 11 years smoke free. I breath easier, can excercise, can walk more than a mile without falling over. Can run up stairs. E-cigs probably saved my life and flavours were an important factor in staying with it.
