Ben Underwood

Ben Underwoodtaught is blind, both of his eyes were removed (cancer) when he was 3. Yet, he plays basketball, rides on a bicycle, and lives a quite normal life. He taught 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 ecos to let him know where the objects are. He’s the only person in the world who sees using nothing but eco location, like a sonar or a dolphin.
