Alastair Campbell co-hosts the UK’s most successful podcast, The Rest is Politics and a huge percentage of the audience is under thirty. He tells Katherine why he thinks he still appeals to the young.

He’s 68 but he’s hoping his biological age will be 21. If it’s not, he’s calling for a recount or an overhaul of the system!

His kids keep him feeling young, but Alastair says it can be challenging being the oldest man in the audience when he’s watching his comedian daughter Grace perform her often explicit set.

He lives a healthy life now but will colitis, stress and past struggles with depression and alcoholism have impacted on his biological age?

Dr Nichola Conlon gives her verdict on Alastair’s result and applauds his commitment to cold water swimming. She explains what happens to the body when you plunge in cold water, and how long you need to be in cold water per week to get the health benefits.

If you want an explainer on how UK politics work, the books Why Politics Matter and Alastair Campbell Talks Politics are available now

Alastair Campbell recorded this before he turned 68.

John and Edward Grimes burst on to the scene in 2009 as a phenomenon on X-Factor, and have been a mainstay on the showbiz scene ever since.

TV, movies, Eurovision: no one can escape this Irish duo's j-epic brand of entertainment.

But what impact has more than 15 years of fame had on the boys as they became men?

Their care-free, feel-good attitude is synonymous with the Jedward brand, but losing their mum at an early age, and playing the fame-game has had its own impact behind the scenes.

Now 33, they've given Katherine Ryan a few drops of their blood to get it tested, so she can find out their biological age.

As twins, their DNA is an exact match, so our resident scientist Dr Nichola Conlon explains how slight variations in diet and mindset could be a reason why their biological ages might differ...

And will the boys get competitive when the results are incoming? You bet!

Katie Price says she’s in a better place than she’s ever been and at the age of 47 is finally fully in control of how she lives her life. She’s been in the public eye since she was 18 years old and with sexual assault, 3 kidnap attempts and a hijack at gun point in South Africa she’s had way more than her fair share of trauma. In this hugely open and emotional interview, she talks to Katherine about her breakdown and the therapy she’s done over the years to deal with the drama she’s constantly lived with. But will the trauma have impacted on her biological age?

Katie talks about her exes, Katherine and Katie bond over the bad men choices they’ve made over the years and Katie admits it’s left her with trust issues. Katie talks lovingly, as always, about her 5 children and her adorable Harvey. She says the door is always open to Dwight Yorke even though he’s never played a part in his son’s life.

Katie is charming and relatable as ever. She says age doesn’t bother her but admits she’s addicted to changing her body through surgery and wants to have another kid.

Dr Nichola Conlon explains the test to Katie and explains how trauma changes your hormones and impacts on your biological age. Katie tells Nichola about her diet and Nichola explains where there’s room for improvement and the supplements she could start taking. Katie is in perimenopause and Nichola talks about how that can also impact on your biological age.

Katie talks about sexual assault, trauma and abuse in this episode which some listeners and viewers might find upsetting. You can find support organisations here:
