Katherine Ryan’s new podcast is set to feature a host of famous famous but there’s one catch - they have to agree to a blood test before they come on.
Sounds a bit odd you might think, but the idea is to determine their “biological age”, as opposed to their chronological age.
The results – based measuring the inflammation in your system –is set to lead to discussions about how we age, what it really means to “feel your age,” fears and positives about aging, and the quirky habits guests may have in the pursuit of health and longevity.
Each week, the Canadian comedian - who according to her birth certificate is 41 - and her guests will also joined by specialist in longevity and cellular ageing, Dr Nichola Conlon.
Dr Conlon will bring 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.
The podcast is set to premiere on all major platforms, including Rayo, Spotify, Apple Podcasts, and Google Podcasts, on April 22.
Ryan - who recently told fans she had been diagnosed with early-stage melanoma for the second time - says she is “excited” about her latest broadcasting endeavour.
Speaking about it, she said: “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?”
Lucie Cave, Bauer Media Audio’s Chief Creative Officer added: ‘We are absolutely thrilled to welcome What’s My Age Again? to our podcast family.
“Katherine has always had a unique ability to blend humour with meaningful conversation, and this podcast takes that to a whole new level. The concept of measuring glycolic age rather than biological age is groundbreaking, and with Katherine’s wit and her celebrity guests, we believe it will be an engaging, entertaining, and educational experience for listeners. It’s truly a perfect match, and I know listeners are going to love this innovative new show.”
