Romesh Ranganathan is 47 but he thinks he’s heading for an early death.

His worries were triggered by a health test 8 years, the premature death of his father as well as the negative health outcomes for Southeast Asian men. But in recent years he’s transformed his health. Will he have done enough to improve his biological age?

He tells Katherine he’s not bothered about getting older and admits he’s getting less ambitious as he ages. He also says that people with regular bodies like him have a duty to show their flesh to counter the images of perfection we are bombarded with on social media.

Dr Nichola Conlon explains how a pre-disposition to poor health impacts on your biological age and whether you can reverse it with lifestyle. She also talks through the supplements that are clinically proven to help with biological ageing and the impact of excess weight.
