How to Stay Young

In this second episode, The Brain, Angela and Chris explore the latest research into ways of keeping the brain healthier for longer. They also look at the science that could help protect against brain disease, one of the fastest growing areas of research, and a subject particularly close to Angela's heart as her mother died of vascular dementia.

In Japan Angela discovers the foods can help protect your brain and meets a 100 year old who is living proof of the importance of diet in maintaining a healthy brain. In the USA Chris is granted exclusive access to a trial where Alzheimer's sufferers are being injected with young people's blood to observe effects on the brain.

The BBC team up with Kings College, London to carry out a unique study into which exercise is best for the brain, putting brisk walking and table tennis head-to-head. The study reveals that after just 10 weeks of exercise actual changes to the structure of the brain can be seen - but which exercise comes out tops in improving brain function?

How To Stay Young features inspirational centenarians, includes cautionary tales and offers tricks and tips to improve the cards we're dealt - all with one ultimate goal to help us live better and healthier lives for longer.

In this first episode, unfit 57-year-old Kamini Sohi discovers how building muscle will not only make her stronger but also protect her against illness. 51-year-old Tim Belton learns that his diet has been stopping him producing hormones vital to ageing well. And 50-year-old Alison Richards finds out a surprising way to tackle memory loss and make her brain younger.

In episode two, we've invited a group of ordinary Brits to our anti-ageing lab to take part in one of Britain's biggest ever ageing experiments to find out their true body age - and the results are shocking. Many of us are ageing much faster than we should be.

One volunteer Kamini (pictured) discovers how being so lazy has made her body weak, putting decades on her age. Fifty year-old Alison finds out why modern life has made her so forgetful, and 51 year-old stress eater Tim has one of the worst results our scientists have ever seen, putting his life at serious risk.

They'll have just three months to get their body age down and closer to their birth age. But will they have succeeded when they re-face the tests in the ageing lab?

In the final episode, 45-year-old Tina Collett discovers the damage her diet is doing to her skin, 49-year-old ex-policeman Rich Jones scores the worst body age seen so far, and 68-year-old Isabella McTaggartlearns how to reverse her brain's decline. If you've ever worried about ageing or wanted to turn the clock back then this programme is going to show you how to do it.
