Most of us want and expect medicine's miracles to extend our lives. In today's aging society, however, the line between life-giving therapies and too much treatment is hard to see--it's being obscured by a perfect storm created by the pharmaceutical and biomedical industries, along with insurance companies. In Sharon R. Kaufman investigates what drives that storm's "more is better" approach to medicine: a nearly invisible chain of social, economic, and bureaucratic forces that has made once-extraordinary treatments seem ordinary, necessary, and desirable. Since 2002 Kaufman has listened to hundreds of older patients, their physicians and family members express their hopes, fears, and reasoning as they faced the line between enough and too much intervention. Their stories anchor . Today's medicine, Kaufman contends, shapes nearly every American's experience of growing older, and ultimately medicine is undermining its own ability to function as a social good. Kaufman's careful mapping of the sources of our health care dilemmas should make it far easier to rethink and renew medicine's goals.
