Katherine Ryan’s chart-topping podcast ‘What’s My Age Again?’ is back to provide you with your weekly dose of laughs, surprise and insight into the world of ageing, wellness and self-discovery.

The prolific Canadian comedian and television personality is asking her celebrity friends: how old are you? How old is your body? And what do you do to stay young? The big reveal comes when they take a Glycanage blood test to find out how old they ‘really’ are.

The first season saw huge guests like Katie Price find out she had a biological age of 70, while the second season featured Natalie Cassidy, Alan Davies, GK Barry, Jameela Jamil and more.

What’s season three about?

In the new season, we find out about a host of famous faces including Ruby Wax, Joe Lycett, Chloe Burrows, Dame Prue Leith and Dani Dyer.

You can also expect weekly bonus episodes hosted by our resident scientist Dr Nichola Conlon, who will be answering listener’s questions about biological age and the aging process.

The first episode is out now and features famous comedian Jimmy Carr. Listen on Rayo, Apple Podcasts, Spotify, Amazon Music or wherever you get your podcasts.

Who is taking the first test this season?

Jimmy Carr is one of the most successful comedians in the country; he’s spent decades touring relentlessly, hosted several Channel 4 television shows, and is still living life at full speed. So how does he look so youthful at 53?

In his episode, Jimmy shares his approach to longevity, from biohacking to fasting and recovery AND mindset and resilience. And of course, we find out if he’s ageing backwards or simply hiding it well when he takes the test.
