Is there an age in which people should couple-up and settle down? Laurie Taylor visits the home of 6 young people who are extending their student sharing habits into their early thirties. What is the factor that keeps an increasing amount of people living like this - is it economics, good friendships or an antipathy towards what other people might regard as growing up? Laurie and his two sociological companions, Esther Dermott from Bristol University and Josh Richards from the University of Manchester accompany him on his investigation. Producer: Charlie Taylor.
