In this Aug. 28, 2010 photo, Associated Press photographer Emilio Morenatti runs during a photo session in a Mexico City public park, one year after he lost his leg during an attack while on assignment in Afghanistan. For those who lost a limb or more in the Boston Marathon, Monday, April 15, 2013, was the day their world changed forever. Morenatti's world changed also, on Tuesday, Aug. 11, 2009, when during his embed in southern Afghanistan with the U.S. military as a photographer for The Associated Press, which was to have been his last patrol before going home, the eight-wheel armored Stryker vehicle where he was traveling in with U.S soldiers hit a roadside bomb and flipped over, knocking him unconscious. Morenatti, who lost his leg below the knee in the bomb blast, says that if those maimed in Boston were to ask him what was harder, the physical or psychological recovery, he would say the two go hand-in-hand. "If you don't confront the feelings of loss, the fact that your world has changed, you never fully recover from the amputation," writes Morenatti. (AP Photo/Ramon Espinosa)
