human echolocation? meet ben!

check out ben, a totally blind young man who (sort of like bats and dolphins) is able to echo-locate his surroundings. what is unique here is that this is not the work of evolution, ben doesn't hve the ears of a bat (nor was he born blind, acrtually he got cancer). yet, he has been able to compensate for his loss. he produces sort of the same bat sounds. amazing!
