Jon Will's Aptitudes is an essay by George Will about his oldest child who was born with Down syndrome.

Jon has Down syndrome, a chromosomal defect involving varying degrees of mental retardation and physical abnormalities. Jon lost, at the instant he was conceived, one of life's lotteries, but he also was lucky: His physical abnormalities do not impede his vitality and his retardation is not so severe that it interferes with life's essential joys--receiving love, returning it, and reading baseball box scores.
