Professor Rose Anne Kenny is one of Ireland’s foremost gerontologists, and one of the senior researchers behind TILDA – the Irish Longitudinal Study on Ageing. She joins Peter Kavanagh to discuss why we needed to gather the huge amounts of data TILDA provided, how we can learn from it, and what older people can do to manage their own health. Professor Kenny’s new book “Age Proof – The New Science of Ageing” will be released in 2022, published by Bonnier Books.
