Sonar Man

Ben Underwood is a man with a vision of the world's first sonar ...
Ben's eyes can no longer be used because it is damaged due to cancer ..
But in everyday life, he was not bothered by that blindness. He can play basketball, ride bikes, play football and so forth without groping blind as appropriate. Why is this so?

Ben trained himself to see with sound (sonar), such as bats, dolphins or sea vessel.
Extraordinary man ..... but unfortunately this sonar had died in January 2009 yesterday.
If it has not died, and was given the opportunity to train other blind people to be able to see this natural beauty with sonar like him:)

Hurray for Ben, and may he find happiness / peace in heaven .... amen


Okay all,, may be useful for all ................!!!!
