The Science of Living a Longer and Healthier Life - Professor Rose Anne Kenny

We all age. But why do some of us live longer than others? And why do we live twice as long today as our ancestors did 200 years ago? And what can the latest science teach us about living longer? Professor Rose Anne Kenny has 35 years of experience right at the top of ageing medicine and has written a book about Aging called - Age Proof. She spoke to Fran on Tipp Today this morning.
