What to if i am just curious, what is worse on the human body, smoking cigarettes or eating process?

Smoking cigs: By far. In fact, internal tobacco company documents have revealed that they are the actual sponsors of some of the foolish / subscientific claims about ways to protect yourself from getting cancer / other risk factors for coronary artery disease, cancer and stroke. My physician / scientist colleagues have all quit smoking and almost none worry about "eating processed foods.".
