A government advisor is warning that adolescent addiction to computer games is set to rise steeply over the next few years.
Jane Whalley's teenage son has received treatment for a gaming addiction. "Jack became very withdrawn," she explains on BBC Radio 5 live. "He stopped going out."
Jack agrees, telling Nicky Campbell on 5 live Breakfast: "I'd just get proper angry, over nothing."
"I just felt proper happy in the game," Jack continues. "It was my own little world."
