Medical ethicist Daniel Callahan. His new book is "The Troubled Dream of Life: Living with Mortality." (Simon & Schuster). In it he looks at how our society views death: If death is a "part of life," why do we have such trouble accepting it? And how do our attitudes about death affect medical and social policy?
Author Daniel Callahan. He is an expert on medical ethics whose latest book is "What Kind of Life: The Limits of Medical Progress." The book questions the assumption that everyone should receive the most life sustaining medical care available. According to Callahan, we need to change our thinking about health and illness and focus on the quality of life rather than the extension of life. (Interview by Sedge Thomson)
