It's no secret that Koreans are some of the hardest workers in the world. From a young age, one spends his or her school days buried in books, memorizing endless pages of material, and hopping from math to English to art academy. There's very little time for play, or childhood even. Things don't change much by the time one reaches the workplace. Of the cities across the globe, those working in Seoul put in the most working hours per week on average. Efficiency has nothing to do with it, but because of their propensity to work hard, they find it necessary to play hard, too. And very few can play as hard as Koreans do.
