This is heartbreaking. This kid was astounding for his courage in the face of a horrible disease and for his incredible intelligence. The world will sorely miss him. It's a real tragedy that children would have to suffer so much or die so young. Link Note: This is a few days old, but I didn't see anything on the forums, so I thought I would post it. Has anyone else seen Mattie on Larry King Live? Over the past few years, he's been on several times and despite his debilitating illness, he was always filled with so much hope, compassion, and joy.
