In How To Stay Young, a two-part series for BBC One, Angela Rippon and Dr Chris van Tulleken travel the world investigating the latest experiments and research that could help put the brakes on the ageing process.
In the first episode, Angela and Chris discover that scientists now know how much of the way we age is down to genetics – and how much of it is down to the way we live our lives.
Angela travels to Germany where she follows a study comparing the benefits of dancing with conventional gym exercises and reveals which activity best keeps us fit and strong into old age. Chris visits a community outside Los Angeles that has one of the lowest levels of heart disease in America and high life expectancy, and looks at how their good health could be down to diet.
The programme goes on to look at what is happening at the frontiers of science to tackle ageing. In Ecuador Chris meets Yannick Castilo, who looks like a young child but is actually 17 years old. He has Laron syndrome and could hold the key to curing ageing, as the syndrome means he is virtually immune from cancer and diabetes and he will never grow old like the rest of us.
