Video: Watch Jon Stewart age 16 years in two minutes

This video won't make pleasant viewing for Jon Stewart's Daily Show successor Trevor Noah.

Stewart has been at the helm of the popular programme for 16 years, and this brilliant time-lapse clip of his tenure suggests reporting on subjects like racism and politics can be stressful. Beginning with a thick head of jet-black hair, a thirtysomething Stewart goes through a decade and a half of presenting duties and various shades of grey, right up until he enters his sixth decade. His barnet goes from raven to silver fox quicker than you can say "Here it is, your moment of zen." Noah has been finding his feet before he takes over from Stewart later in the year, but now the 31-year-old will start out in the knowledge that his hair will never be the same again. https://www.youtube.com/watch?v=EC0Xfv433n8
