Most of us would like to live for as long as possible, given we’re in good health. But the definition of a long life is changing, and the rapid advancement of anti-ageing technologies could transform the idea of immortality from fantasy to reality. So the question isn’t so much can we live forever, but should we? Anna Machin talks to Dr Stephen Cave, Director of the Institute for Technology and Humanity at the University of Cambridge, and co-author of Should You Choose To Live Forever? A Debate, to find out. • “If we’re serious about pursuing longer lives, we have to get really, really serious about making those lives sustainable”.• “With life-extension and anti-ageing technologies, the effects will be enormous. Many of them will be beyond what we can imagine right now. If we’re going to pursue them, we need to think of what we can do to maximise the benefits, and manage the risks.” WHY? is written and presented by Anna Machin.
