Baseball

A baseball outfielder does not calculate where a fly ball will land. They simply run while keeping their line of sight to the ball at a constant angle. Falcons hunting ducks use the same method. This instinctive tracking is called the gaze heuristic.

Dizzy Dean, a Baseball Hall of Fame inductee who retired at 31, became a commentator known for relentlessly criticizing players. His team eventually put him on the mound to prove his words. At 37, six years after retirement, Dean pitched four scoreless innings.

In 1951, Eddie Gaedel, just 109cm tall, appeared in a Major League Baseball game. His strike zone was only 3.8cm high, making strikes nearly impossible. He walked on four pitches and was replaced immediately. His career on-base percentage: a perfect 1.000.
