"Your life can change in a second," says Mohamed Massaquoi, former UGA and NFL wide receiver. And Mohamed would know. A freak ATV accident led to the amputation of his left hand, and the close of his career.

With 12 surgeries behind him, and a whole new life ahead, he says, "You don't really understand, conceptually, how fragile time is, how fragile life is, in terms of 'Every moment matters.' But let me appreciate the moment that I'm in because once it passes, it may not come back." Hear Mohamed's story

Producer note: On the day of the shoot, Mohamed forgot the battery to charge his bionic hand. So it didn't move at all. He was incredibly gracious during the interview, but it still kills me not to have had that visual.
