Six well-loved British celebrities take part in an experiment that explores the prevention of ageing. Find out what happens beyond the experiment, and how it has changed the celebrities’ lives.

What if it were possible to turn back time? Could it be that we have the power to think ourselves young again? That’s the extraordinary claim of an experiment first conducted 30 years ago which the BBC re-staged.

Six well-loved British celebrities – Liz Smith, Lionel Blair, Dickie Bird, Sylvia Syms, Derek Jameson and Kenneth Kendall – have agreed to turning back the clock. For one week they will live, work and eat in the 1970s to see if they can regain their youth.

The changes were amazing. And I’m not easily amazed.

Dr. Michael Mosley, Host, The Young Ones

In 1979 psychologist Ellen Langer from Harvard University conducted a unique experiment to find out what would happen when a group of eight older men were given the experience of living 20 years earlier. She and her team created a living environment complete with food, films, photos from the period. The group discussed news, politics and sport in the present tense as if they had travelled back in time.

Astonishingly the group became physically and psychologically younger. Their hearing, grip strength and manual dexterity improved. Memory and IQ scores also improved. Because their minds were actively engaged in living 20 years earlier, their bodies seemed to follow. Ellen believes this is a demonstration of how our bodies don’t let us down as we get older, it’s our minds that accept the labels of aging. Freeing ourselves from that state of mind can turn back the clock.

Sylvia Syms – Age at the time of experiment: 76

When I came in, I was in considerable pain. My back was painful all the time. I could barely walk. Now for some obscure reason, I cannot tell you why, that has improved. I also know that my trousers are looser [chuckles].To see the change in you [Liz] and see that you lost some of your fear of walking without your stick is tremendous. That is a joy for all of us, I think.
