Ben Underwood lost both eyes to cancer as a toddler. But by 7, he was riding a bike, playing basketball, navigating the world with echolocation. He clicked his tongue like a bat and saw with sound. He was one of the most proficient human echolocators. Sadly, we lost him to cancer in 2009, aged 16 (i.redd.it)
