Katherine Ryan is set to launch her new podcast, What's My Age Again? Episode 1 is out 22nd April at your usual podcast outlets.

It aims to be a  refreshing and humorous take on ageing, wellness, and self-discovery.

Katherine Ryan says: ‘In a beauty-obsessed society that rewards aesthetic youth, what about the far more impactful biological vitality? As a pretty clean-living autoimmune disease sufferer with loads of inflammation, I’m excited to be investigating cutting-edge technology that tests glycolic age with a mix of my celebrity friends. Are they biologically older or younger than they think they are? What can we all be doing differently to extend our lives? Who will be willing to give me their actual blood for a podcast?’

The podcast features interviews with some of the UK’s most famous faces, who have all undergone a blood test to determine an accurate reflection of their biological age, as opposed to their chronological age. The results – often surprising, sometimes shocking – lead to hilarious and thought-provoking discussions about how we age, what it really means to “feel your age,” are they afraid of growing old, the pros and cons of ageing and the quirky habits they may have in the pursuit of health and longevity…

Each week, Katherine and her guests are also joined by Dr Nichola Conlon. A specialist in longevity and cellular ageing, Nicola brings her scientific know-how to interpret the test results and provide listeners with the latest research in the field.

The first episode sees Irish comedian and podcaster Joanne McNally taking the test; whilst future guests include Olivia Attwood, Adam Buxton, Jill Scott, Bryony Gordon, Dame Sheila Hancock, Sophie Ellis Bextor, Alastair Campbell and Dame Denise Lewis.
