For my final guest of Season 3 I was so thrilled to be joined by Prof Rose Anne Kenny, Chair of Medical Gerontology at Trinity College Dublin and founding PI of TILDA the Irish Longitudinal Study on Ageing - Irelands largest adult population study on ageing. She chats to me about her early medical influences, why she wanted to pursue a career in geriatric medicine and her return to Ireland after many years in the UK. We chat about how and why she undertook the TILDA project, the success stories to come out of this 12 year ongoing study and how it has informed government policy. Rose Anne also chats about the importance of Vitamin D for healthy and healthy ageing and how the secret to success is about having a 'fantastic team'. This is episode marks the end of Season 3 of Unravelling Science. I will take a quick break for the summer but I will be back in the autumn for Season 4 and plenty more stories that shaped the science!
