The Young Ones - Episode Guide

In Episode 1, our celebrities settle into the past, hoping they'll achieve their personal goals to turn back the clock - and within the first 24 hours there are already extraordinary changes.

In Episode 2, each of the celebrity volunteers must come face to face with the lives they led in their heyday and take back control of their lives. For Lionel, the most resistant to the experiment, a trip to the London Palladium ends in tears, and for Dickie a trip to Lord's cricket ground brings the man he used to be back to life. Kenneth is reacquainted with his beloved dogs, and Liz takes up painting again.

But just as the experiment seems to be working, a surprise visit from a group of carers shows Michael and Ellen just how far the volunteers still have to go...

It is the final day of the experiment, and the last chance for the volunteers to achieve their goals. In one final goodbye to 1975, a dinner party will be a chance to test how far each of them has come, and to see whether they really have turned back time. Undergoing the tests once again, what will the science say?

In an emotional closing episode, each of the volunteers must say goodbye to 1975, and will discover whether they've really managed to turn back the clock. We'll see how their lives have changed since the end of the experiment - has it given them a new lease of life, or are they back to being just another old person in 2010 Britain?

In this special, Michael Mosley explores the science behind the series, and tests the idea that we have control over how we age. The programme puts Britain under the microscope to see how our environment, our preconceptions about old people and how we behave ourselves can have enormous impact on how we feel about the elderly and how we ourselves age. A state of the nation programme which shows the remarkable science and extraordinary truths behind the series.
