Usage Note: Some people insist on maintaining a distinction between the words healthy and healthful. In this view, healthful means "conducive to good health" and is applied to things that promote health, while healthy means "possessing good health," and is applied solely to people and other organisms. Accordingly, healthy people have healthful habits. However, healthy has been used to mean "healthful" since the 1500s, as in this example from John Locke's Some Thoughts Concerning Education: "Gardening ... and working in wood, are fit and healthy recreations for a man of study or business." In fact, the word healthy is far more common than healthful when modifying words like diet, exercise, and foods, and healthy may strike many readers as more natural in many contexts. Certainly, both healthy and healthful must be considered standard in describing that which promotes health.
Do you smoke even a little? If so, know this: “Smoking even a single cigarette can induce changes that lead to a heart attack,” Gianos says. Lighting up increases your risk of atherosclerosis, raises your chances of blood clots, reduces blood flow and puts you at increased risk for stroke. But it’s never too late to quit and start reversing the damage. “Heart disease risk goes down 50% in the first year [after quitting] and becomes equivalent to a nonsmoker after 10 years,” Gianos says.
Before the development of medical expense insurance, patients were expected to pay health care costs out of their own pockets, under what is known as the fee-for-service business model. During the middle-to-late 20th century, traditional disability insurance evolved into modern health insurance programs. One major obstacle to this development was that early forms of comprehensive health insurance were enjoined by courts for violating the traditional ban on corporate practice of the professions by for-profit corporations. State legislatures had to intervene and expressly legalize health insurance as an exception to that traditional rule. Today, most comprehensive private health insurance programs cover the cost of routine, preventive, and emergency health care procedures, and most prescription drugs (but this is not always the case).
Health insurance is insurance that covers the whole or a part of the risk of a person incurring medical expenses, spreading the risk over a large number of persons. By estimating the overall risk of health care and health system expenses over the risk pool, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to provide the money to pay for the health care benefits specified in the insurance agreement. The benefit is administered by a central organization such as a government agency, private business, or not-for-profit entity.
