I've never met a single smoker with hormone problems. My excercising gives me a strong heart and low cholesterol. I doubt I'm going to have insulin problems. there are some medical people in my family and as far as I remember talking about diabetes, because several memebers ofmy family have it, smoking has nothing to do with causing it. smoking is just a little bad for you everywhere. but excersie is good for you in a host of ways.
it's acumulative life style. everything counts and adds up. smoking or not smoking is the be all of taking care of yourself. there is your food intake, which city you live in even based on pollution, and excerise which makes more of a difference than anything else. I don't doubt for a second that living in chicago is worse for your lungs than smoking. just go there once and take a breath of the not so fresh air. It will make you throw up if your not used to it.
