Exactly. I was a dancer for a long time and I smoked. Smoking never hindered me one bit.
As long as a smoker keeps up cardio and good eating habits and maintains a good weight, what's to worry?!
Smoking is a risk but I think you can make a case that being sedentary and overweight is an even bigger risk. In any case, couch potatoes have no stand to take pot shots at smokers!
I have a smoking brother-in-law who works construction and does a lot of active sports. He's trim and healthy looking at age fifty-two. I wonder if you can burn up some of the the tar, etc with aerobic exercise.
