'Big changes are coming in every aspect of our lives. Should and will we embrace or reject them? (This) well-chosen collection of short but eye-opening essays will help you decide which choice is made.' Gregory M. Fahy PhD, cryobiologist, biogerontologist and former Director of the American Aging Association'The whole idea of human enhancement divides people. The cautious emphasize the dangers of the techniques themselves, and the social and political consequences of allowing individual choice and commercial interests to prevail. Enthusiasts point out that humans have always striven to enhance human capabilities and extend lifespan. Isn't it unethical not to seek to improve on nature? This book deepens the debate, with perspectives from diverse disciplines and cultures explaining what the technologies are, what they might achieve and the societal consequences on a global scale.' Dr Mairi Levitt, Department of Philosophy, Lancaster University
