We are living through an exciting revolution in biology. Giant strides are being made in our understanding of why we age, and why some species live longer than others. Will we soon be able to cheat disease and death and live for a very long time, possibly many times our current lifespan?

Why We Die shares the latest scientific understanding of what causes ageing and how we might prevent it. Ramakrishnan examines the cutting-edge efforts to extend the human lifespan by altering our natural biology, raising profound questions and unravelling mind-bending answers along the way. Does death serve a necessary biological purpose? What will it mean for us all if some people start living longer? And how can we increase our chances of living long, healthy and fulfilled lives?
