I love this photo from National Geographic (yes, I've been reading in the bathroom). The caption reads:
Bhutan Novices at the Dechen Phodrang monastic school in Thimphu hear the dinner bell and come running. More than 400 boys attend the academy, where a typical day of study stretches from 5 a.m. to 9:30 p.m.
That is one h*ll of a long school day, no wonder they're running to dinner. But look at their faces. They look truly happy. I bet they're learning good stuff, important things for the soul.
