A doctor can't keep you out of dangerous situations that are hazardous to your health. They can't exercise or watch your weight or quit smoking or take your medicine for you. They aren't there to notice the first symptoms of a disease. And you'll get worse results if you don't describe your symptoms accurately.
Of course they'll still do the best they can for people who don't do any of these things, but people who take care of themselves (or have other people - amateurs - to advocate for them) are going to get better use out of the medical system.
