Like all other presidents, the office has taken its hair-color toll on Barack Obama.
On the other hand, my hair is distinctly grayer than it was six years ago, too. My life has not been nearly as stressful as the average president's in a term-and-a-half, though, and I don't know that I'd be willing to trade lives. (Okay, yeah, I'd trade lives in a heartbeat, but that's purely ego talking.)
