But of course as one of your links points out:
The term "preventive medicine" no longer means what it used to: keeping people well by promoting healthy habits, like exercising, eating a balanced diet and not smoking. To their credit, both candidates ardently support that approach. But the medical model for prevention has become less about health promotion and more about early diagnosis.I'm pretty sure the original comment you replied to assumes the same meaning, that of promoting healthy behavior _before_ you become ill, not the newer and distorted meaning of "early detection".
