Jai Alai is one sport that requires really fast reflexes.
Thrown with a curved wicker cesta, the rubber and goatskin ball can rebound at a speed more than twice as fast as a baseball pitcher’s fastball, as fast as 188 miles per hour.
Getting hit by one can be fatal.
Between 1920 and 1967, before helmets were introduced, at least four players were killed by jai alai balls to the head.
The Basque Government promotes jai alai as “the fastest sport in the world” because of how fast the balls are thrown.
