  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.

• Sandro Farmhouse – will the Bake off’s star’s biological age be another show stopper or a wet sponge?

  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.
