Alistair Fraser talks about teenagers, street life and filling time. Doing nothing has become the mantra of twenty-first century life. In an accelerated world, we yearn for a space where minds are emptied, iPhones left at the door. But doing nothing is not always a choice. For young people, bored on the streets, it's all there is. And for them doing nothing is always doing something. New Generation Thinker Alistair Fraser, from the University of Glasgow, has written books including Gangs and Crime: Critical Alternatives and Urban Legends: Gang Identity in the Post-Industrial City, which was awarded the British Society of Criminology Book Prize.

Recorded with an audience at Sage Gateshead as part of BBC Radio 3's Free Thinking Festival.

New Generation Thinkers is a scheme run by BBC Radio 3 and the Arts and Humanities Research Council to select ten academics each year who can turn their research into radio.
