Goalball players bowl a two-and-a-half pound medicine ball at speeds of up to 40 mph toward opposing team members.
Imagine you're blindfolded on a gym floor. Across the room, someone is about to bowl a two-and-a-half pound medicine ball straight at you, at speeds of up to 40 miles an hour. What do you do? If you play goalball, you throw yourself on the ground to block the ball and prevent the other team from scoring. It's a sport specifically designed for the blind and visually impaired.
