Are the worlds oldest people really that old?
Madeleine Finlay speaks to Dr Saul Newman, an interdisciplinary researcher at University College London and the University of Oxford, who has just won an Ig Nobel prize \u2013 given to scientific research that \u2018first makes people laugh, and then makes them think\u2019 \u2013 for his work showing that many claims of people living extraordinarily long lives come from places with short lifespans, no birth certificates, and where clerical errors and pension fraud abound. He tells Madeleine what happened when he went looking for the world\u2019s centenarians, and how his work has been received by the longevity research community.
