THE BOY WITH SONAR VISION (Ben Underwood)

Ben Underwood is blind. Both of his eyes were removed because of when he was 3. Yet, he plays basketball, rides on a bicycle, and lives a quite normal life. He teached himself to use echo location to navigate around the world. With no guide-dogs, he doesn't even need hands : he uses sound. Ben makes a short click sound that bounces back from objects. Amazingly, his ears pick up the echos to let him know where the objects are. He’s the only person in the world who sees using nothing but echo location, like a sonar or a dolphin.
