Diagnosed with retinal cancer (http://en.wikipedia.org/wiki/Retinal_cancer) at the age of two, American Ben Underwood had his eyes removed at the age of three <sup id="cite_ref-11" class="reference">[12] (http://en.wikipedia.org/wiki/Human_echolocation#cite_note-11)</sup>
He discovered echolocation at the age of five. He is able to detect the location of objects by making frequent clicking noises with his tongue. This case was explained in 20/20:medical mysteries. <sup id="cite_ref-12" class="reference">[13] (http://en.wikipedia.org/wiki/Human_echolocation#cite_note-12)</sup> He used it to accomplish such feats as running, basketball, rollerblading, playing foosball (http://en.wikipedia.org/wiki/Foosball), playing video games, and skateboarding.<sup id="cite_ref-13" class="reference">[14] (http://en.wikipedia.org/wiki/Human_echolocation#cite_note-13)</sup><sup id="cite_ref-14" class="reference">[15] (http://en.wikipedia.org/wiki/Human_echolocation#cite_note-14)</sup>
Though at first resistant to using a cane for mobility, seeing it as a "handi-capped" device, and considering himself "not handicapped at all", Daniel Kish demonstrated to Ben how he utilized his white cane combined with echolocation to further expand his mobility, though Ben never adopted this method.<sup id="cite_ref-autogenerated2_10-1" class="reference">[11] (http://en.wikipedia.org/wiki/Human_echolocation#cite_note-autogenerated2-10)</sup>
Ben died on January 19, 2009 at the age of 16. He died from the same cancer that took his sight.<sup id="cite_ref-15" class="reference">[16] (http://en.wikipedia.org/wiki/Human_echolocation#cite_note-15)</sup>
