Welcome to What’s My Age Again – the podcast that asks: How old are you? How old is your body? What do you do to feel young Katherine Ryan not only asks her celebrity guests how they feel about ageing but she also asks them to give her their blood; Every famous name on the show takes a biological age test and midway through the show we reveal how their bodies' age compares to their chronological age. It’s a fascinating and fun conversation about their lifestyle, their childhood, their family and their attitude to getting older. Do they do anything to reverse the visible signs of ageing? The guests span the decades, and we find out if years of being at the top of their game in sport, entertainment or politics has impacted their body. Dr Nichola Conlon, who has a PhD in biochemistry joins us every week to discuss the guests’ results and to share the latest science on longevity.
