The teenage bedroom has been granted a decade-long extension, as have all manner of pubescent mores. According to a 2015 survey by the Office for National Statistics, one fifth of 25 to 29 year olds in Britain still lived at home with their parents.

For better or worse, the economy has thrown a scrunchie in the works and, at least in the UK, the normative route to adulthood – choosing a career and a partner, buying a home and filling it with kids – has become unaffordable for a considerable chunk of the population. ‘Teenage’ no longer just refers to that period between the ages of 12 and 20.
