The phrase disease mongering was coined by medical and science writer Lynn Payer in her 1992 book Disease-Mongers: How Doctors, Drug Companies, and Insurers Are Making You Feel Sick. Payer defined this deceitful practice as “trying to convince essentially well people that they are sick, or slightly sick people that they are very ill.”

It’s normal for a 50-year-old’s density to be less than a 30-year-old’s, and it’s ridiculous to measure the bone density of a 70-year-old against that of someone four decades younger. But at the conference, it was decided that anything below this peak density number was “abnormal” and in need of treatment..."
