FILE - In this Thursday, April 18, 2013 file photo provided by the Hern family, first lady Michelle Obama, right, visits with Aaron Hern, lower left, his parents Alan and Katherine, and sister Abby, all of Martinez, Calif., at Massachusetts General Hospital in Boston. The 11-year-old boy was one of more than 180 people injured in Monday's explosions at the finish line of the Boston Marathon. One week after the bombings, all of the people injured in the blasts who made it to a hospital alive now seem likely to survive. The remarkable, universal survival of those injured is a testimonial to fast care at the scene, on the way to hospitals, then in emergency and operating rooms. (AP Photo/Hern Family, File) less
