Secrets of ageing: how long could I live?

Humans have always been obsessed with getting old, or rather
staying young, and now science is beginning to catch up. Longevity
has become a hot topic from university laboratories to Silicon
Valley startups. In the second of a special Science Weekly
three-part mini-series on ageing, Ian Sample talks to Venki
Ramakrishnan, winner of the Nobel prize in chemistry and author of
the book Why We Die. Venki outlines the most promising scientific
advances in the field of longevity and discusses the more unusual
ways that the wealthy are trying to extend their lives, from blood
transfusions to cryonics. Help support our independent journalism
