Hey, I had a great-aunt. She smoked two packs a day until she was in her 80s. So - that disproves that smoking is bad for you, right? Smoking didn't shorten her life! For every lady like my great-aunt, there are a dozen or more who died much younger from more familiar complications related to smoking (emphysema, lung cancer, heart attacks). There's no dispute - the statistics and data are clear on that point. Obesity is exactly the same thing. In addition, being obese is disgusting and a sign that you have no self-control. So, there's that, too.
