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 has 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 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.
