Where does life begin and end? Who makes the medical decisions that determine human longevity? How far should we go to conceive and what is on the horizon for human reproduction? To address these tough questions, Dr. Oz is joined by Dr. Arthur Caplan, the Emmanuel and Robert Hart Professor of Bioethics, chair of the Department of Medical Ethics and the director of the Center for Bioethics at the University of Pennsylvania in Philadelphia. He is also the author and/or editor of 23 books, including Who Owns Life?, Finding Common Ground: Ethics and Assisted Suicide, The Ethics of Organ Transplants and Am I My Brothers Keeper?.
