So let me see if I've got this straight, cos I encounter this logic on regular basis in ireland. If the doctor says you've got to stop your 100 smokes/day habit, and he said that 3 years ago and nothings happened since, then, (a) he's a doom predictor/monger, and (b) you'll never die of lung cancer.
So therefore he wrong. The only logical thing to do is to ignore this obvious nonsense advice and enjoy smoking even more. What the hell does he know anyway, right?
Well assuming that the doctor knows what he's talking about, wouldnt you think, despite the fact that you're not coughing blood and can breathe fine, that your risks of cancer are even HIGHER today?
