Physicians and scientists around the world even go as far as to state that smoking leads to premature death. Don’t we all know someone who smokes constantly, even heavily, yet is still living — or has lived — to the mature age of eighty, ninety, and older? Furthermore, the MDs and PhDs state that smoking causes cancer and emphysema. If this diagnosis were definitive, wouldn’t these afflictions affect all smokers equally, rather than the small percentage that it actually does affect?
