We've been tantalised by the idea of eternal youth since time immemorial. We're always asking how we can live longer, and better. Or, to put it another way, why can't we all be like Madame Calment who cycled till she was 100, smoked till she was 117 and died at the wonderfully old age of 122?

Join veteran reporter Bill Gifford for a rip-roaring ride along the trail to the fountain of youth. Meet the scientists who have doubled the life-expectancy of mice by knocking out a single gene, and others like Aubrey de Grey, who claims that we are on the cusp of achieving 'longevity escape velocity', and who predicts that our children could live for a thousand years. An intoxicating mixture of deep reporting, fascinating science and sound advice, Spring Chicken will reveal the extraordinary breakthroughs that may yet bring us eternal youth, while exposing the dangerous deceptions that prey on the innocent and ignorant.
