Meet Daniel Kish, at the age of one, he was diagnosed with Retinoblastoma so doctors had to remove both his eyes.
At the age of two, he began to discover ways of 'seeing' his world like most blind childs do, stomping with his feet, snapping fingers, clapping hands, and making clicking sounds.
Now, at the age of 44, Daniel is a fully independent person with the help of a method he called "Flash Sonar" or more commonly known as echolocation.
This technique which is also employed by bats and dolphins enables him to "see" everything around him. Using echolocation, Daniel is able to ride a mountain bike through streets with heavy traffic and on dirt trails, climb trees, camping, travelling, cooking, swimming and dancing. In short, he can do what sighed people can do. In fact, he's accomplished more than most people have accomplished.
