In the first episode Angela and Chris discover 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. They look at the latest science that reveals the best lifestyle choices we can make to combat the effects of ageing. 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. Chris turns 80 years old for a day thanks to Hollywood-style prosthetics. Since how we feel about old age is hugely influenced by society’s treatment of the older generation, Chris decides to experience the public’s reaction to the elderly first-hand. Chris takes a newly pioneered test that reveals on a molecular level how quickly his body is getting old, by comparing his biological age with his actual age. Will his body be as young as he feels, or older than it should be?

Taking a look at the science that could help protect against brain disease, one of the fastest growing areas of research, and a subject particularly close to Angela’s heart as her mother suffered from vascular dementia.
