Wow, that's truly the nanny state at work. I like tobacco, I enjoy smoking and I'm working on my weight. I hate it when I go to a physician's office and get offered the standard blurb about how smoking tobacco is apparently only slightly less lethal than mainlining cyanide with an arsenic chaser.
Frankly, that's a major reason why I don't bother going to see one. My body's working well enough, and while it'd be nice to know that my organs are in good condition, I don't want to deal with someone who doesn't respect me.
Why the fuck are you going to a doctor if you don't want advice that will treat your illness?
And this is the point: a lot of health problems are preventable, and it is your doctor's job to tell you how to avoid those health problems.
But then of course my comment was at least in part sarcastic. An advice can always be a good thing; on the other hand, my first reaction at the idea is to think that I'd like my doctor to listen to whatever health issue I have and solve it, rather than giving me paternalistic advice. As if we didn't have enough already.
