In the first bonus episode of our new series of Dr Nichola’s Second Opinion, resident scientist Dr Nichola Conlon is back in your feed with more of the science behind What’s My Age Again?

This time she’s unpacking biological age tests: what they measure, how they work, and what they can really tell you about your health.

Dr Nichola explains why we all have two ages (chronological and biological) and how the show’s go-to GlycanAge test reads patterns to reveal how fast – or slow – your body is really ageing.

Listener questions take us from pollution and skin ageing, to healthspan vs lifespan and “inflammaging.”

And it’s back! Each week we sign off with Dr Nic’s Quick Fix.

This week: How to choose the right test and use results for insight rather than anxiety.

Send in your questions using our socials and we could be answering them soon on Dr Nichola’s Second Opinion.

Comedian Jimmy Carr looks suspiciously youthful at 53, despite spending decades touring relentlessly and living life at full speed. Is it the Botox? Hair transplant? Intermittent fasting? Cold plunges? Probably all of the above.

But behind the jokes is a serious question: which of these habits actually make a difference? And how old is Jimmy on the inside? 

We’re constantly told the secret to staying young is diet, exercise or the latest wellness trend. But what if the real answer lies somewhere deeper, in how we deal with stress, ambition and purpose?

Jimmy shared his approach to longevity, from biohacking to fasting and recovery AND mindset and resilience, we're joined by Dr Nichola Conlon, verified science woman, who uncovers the science about staying younger for longer.

And we'll answer the question on everyones lips : Is Jimmy Carr ageing backwards… or just hiding it well?

There’s a new take on things for this episode as Katherine welcomes Tim Spector onto the podcast – the first guest who is no stranger to the Glycanage blood test. Tim has been tracking his biological age for several years, so there is more data to discuss with Dr Nichola, as they delve into how his internal age has changed over time and the various things he was doing to shift the needle.  

With Tim’s new book Ferment: The Life-Changing Power of Microbes out now in all good bookshops, expect to hear all the latest science about our gut microbiomes, Tim’s predictions for wellness trends, and more personal stories about how he recovered from a health episode in 2012 and how a fast food experiment with his son had a lasting impact on his son’s microbiome.  

Listen now to find out how Tim’s biological age reflects his knowledge and advocacy and hear what he has to say about how your diet could impact your biological age. 

In this bonus episode, our resident scientist Dr. Nicola dives beneath the surface of cosmetic procedures to explore how modern treatments are evolving—from masking aging to actually targeting it at the cellular level.

Discover the science behind biohacking, fillers, skin boosters, and polynucleotides (yes, the “salmon sperm facial”)

We'll hear how these treatments affect your skin’s biology, and hear listener questions answered on long-term Botox use, microneedling and the impact of dermal fillers.

Plus, Dr. Nic’s Quick Fix offers three practical takeaways to support healthy aging from the inside out.

If you're thinking of undergoing any procedures, or changing your diet to start your own "biohacking" journey, do seek advice from a trained medical professional, and make sure anyone conducting the procedure is trained, and linked to a licensed body.

Katie Piper spent the second half of her twenties recovering from a violent acid attack, and coming to terms with how her life had permanently changed. Nearly two decades on, her life couldn’t be more different.  

In this wide-ranging conversation, Katie and Katherine cover being a wayward teenagers and how attitudes to alcohol change as you age, the false and short-acting currency of beauty, and how she found faith after her life-path was changed at 24.  

As Katie observes in her 2025 book Still Beautiful, age is a gift not everybody is given, which is why she’s very happy for journalists to print her real age. She doesn’t think that traumatic life events have added to her biological age, but the day-to-day reality of being married with children may well have. Listen to this episode of What’s My Age Again to find out how accurate her predictions were. 

In this bonus episode of Dr. Nichola’s Second Opinion, Dr. Nichola Conlon gets into the science behind the hormonal shifts that come with aging, especially during perimenopause and menopause.

She'll explain how hormones like oestrogen and progesterone impact everything from mood and sleep to skin and bone health, and why menopause isn’t just a symptom of aging—it can actually accelerate it.

She'll break down the science behind how HRT can reverse some of the effects, and shares practical lifestyle tips to help you feel better and age smarter.

Plus, your questions tackle everything from early menopause to visible aging and the real benefits of HRT.

Whether you're navigating hot flushes or just curious about aging better, this episode is packed with insights you won’t want to miss.

He didn’t win the final but Sandro Farmhouse was the star of The Bake Off 2022. 

He takes Katherine behind the scenes and reveals it’s not all sprinkles and icing on the show and tells her the lengths he went to, to get in that infamous tent. 

He’s made cakes for Little Mix, Katherine and hiss show-stopper for Stormzy brought him lots of new followers though not necessarily for the right reason.  

 Sandro’s early years were in Angola and he talks openly to Katherine about how fleeing war has impacted on him and Katherine’s concerned, trauma at a young age, may play out in his biological age.  

Nichola delves into his exercise routine and promotes a balanced approach.  Sandro argues abs are more important than biological age and Katherine sort of agrees.  Sandro admits he still licks out the bowl on occasions and Nichola explains for people prone to a sweet tooth, the healthiest way to consume sugar.

 Having spent her twenties feeling she was both too much and not enough, at 35 Rosie Jones is happy with her age. She talks about growing up with cerebral palsy and how her parents never made her feel any different  - but how it did take her until 4 to get off her arse and start walking! 

She’s making up for it now – a successful writer, stand up and actor – she regularly works 16 hours days.  Her and Katherine discuss whether women, especially ones living with a disability – need to work those extra hours to earn a place at the showbiz table.  

It’s a funny, fascinating insight into the world of Rosie.  She never orders soup in restaurants but tells us how she admired a man she met recently with CP who did.  

Rosie tells Nichola about her diet and says her disability makes home cooking difficult but when she is at the fancy restaurants, she does order vegetables.  Rosie often has late nights so she can see her girlfriend and though sleep is good for biological age, Nichola also explains the importance of human connection.
