You're right, I would sympathise more with someone who has anorexia than someone who is obese, is every cry for help really equal to you? If so then I'm very impessed but quite sure you'd find yourself in the minority. And yes, I am superficial, if I got to know the guy I might think I had him totally wrong and that he was absolutely deserving of my utmost concern, but without knowing him I stereotype, I know in many cases it may be wrong to do so, but in a lot it's right too.
I do apologise for my KFC comment if it caused offence, it was, as Yoda would say, "ridiculous hyperbole", I'm sure most only eat 2 or 3.
As for cancer, I see what you're getting at, but we both know they're not comparable to a smoking addiction/alcholism. For one thing the big label on a pack of cigarettes warning that they will kill you probably isn't found on your deodorant or sexual partner, the latter of which I was under the impression tended to increase one's lifespan, provided it isn't undertaken as a string of one-night promiscuities. Your sister, well, I can't expect you not to spend time with her, my best friend has just given up smoking and I didn't abandon him when he did smoke, although I gave him a fair amount of **** for it and I'd like to think that contributed to him kicking the habit. Oh, and eat more fruit.
