Ben Underwood lost both of his eyes to cancer when he was 3 years old. And yet, as a teenager, he could do this.
He got around without a cane or a guide dog, using only his extraordinary hearing.
Underwood used echolocation to see. He would make a sharp clicking noise with his tongue, and could tell from the echo where he was, and even what objects were around him.
His little brother didn't even know he was blind at first.
It didn't make much of a difference, after all.
So his parents just treated him like any other kid.
A pretty amazing kid, that is.
Underwood didn't think of himself as different.
Tragically, the cancer that took his eyesight returned when he was 16, and he passed away.
Underwood's mother shared an inspiring letter to people around the world who were touched by his story. She said: "I pray that each one of us [has] truly taken a piece of this experience, in knowing Ben, and [used] it to become better human beings to one another."
