In the documentary “Waiting to Rise,” Rob Roozeboom’s small son asks him, “Dad, why do you walk like that?”
“Because I have muscular dystrophy, son,” he answers.
The boy is unconvinced. “Penguins walk like that,” he observes, “but they don’t have muscular dystrophy.”
At this stage of his life, Roozeboom, 33, can laugh uproariously at that assessment. But as a boy himself, and later as a teen, his disability was no laughing matter.
