A look at how, during the Noughties, an ageing Britain focused on recapturing its youth. The first of three films exploring what it was like to live through the last decade, and the surprising, often hidden connections which are shaping the 21st century. During the Noughties, an ageing Britain became obsessed with recapturing its youth. The result: trends and fads such as kidults, micro scooters and 'middle youth'. But at the same time, the generation gap emerged as the most significant split in society. While older people pursued a more youthful image, real young people were demonised as 'hoodies'. Reflecting on the decade we spent 'growing young' are a host of leading commentators and experts including Andrew Marr, Tanya Byron and Will Self. Along the way we discover how rave culture led to binge-drinking, learn about Britain's 'baby gap', and find out why downloads saved the Millennium Dome.
