Welcome to What’s My Age Again – The Only Podcast That Takes Your Blood! …and uses it to determine how old your body really is.
Katherine Ryan takes a forensic look into her celebrity guests' lifestyle, relationships, medical history, mental health and anti-ageing rituals (or lack of) before revealing how all this has affected their biological age, and how it compares to the number on their birth certificate.
Diving into the science behind the (sometimes) scandal, Dr Nichola Conlon, who has a PhD in biochemistry, is on hand to decode the results, separating the science from the snake oil and explaining what they can actually do about it.
Catch up on episodes with Katie Price and Vogue Williams, and follow the podcast for new episodes with Louis Theroux, Vicky Pattison and more.
The test is carried out by the company Glycanage.
