My dad is 78 years old, smokes about a pack a day (cut down from 2 packs when he was younger) and his respiration is that of a 35 year old according to his doctor. Of course, my dad played racquetball for something like 20 years and still works out 3 to 5 times a week, so maybe it’s something about not exercising the smoke out of your lungs that leads to cancer, emphysema and such. My mother, who was also a smoker, had lung cancer was treated for it, had it return 10 years later, and died of a heart attack. So I agree that cigarette smoking is a factor in respiratory and cardio-pulmonary ailments, but it’s not the only factor.
