If, after leaving school in the early 1990s, you announced to your parents that you were taking some time out from the daily grind and leaving hearth and home to explore the world and broaden your mind, you would most likely have received a pair of horrified stares. This might be followed by a barrage of expletives regarding an expensive education being flushed away, and a stream of invective on a presumed new life of drug taking and trafficking.

A lot has changed in 15 years. Nowadays it is practically taboo to deride the idea of a gap year - to ban your children from taking one is close to abuse. For the majority of 18 to 24-year-olds, a year away from the pressures of the library has become a rite of passage. And whether it be spent conserving watering holes in Tanzania or drinking from them in Australia, the general consensus of clichés is that a break from education provides an opportunity to find oneself and form a wider perspective on life.
