blind as a bat - I think not!

saw something interesting on AXN tonight, on 'Ripley's believe it or not' - had to share it. Echo locators. Bats use 'em, dolphins use 'em, and apparently some extraordinary humans use 'em too! Bats use echo location, similar to sonar, for locating food and navigating through the darkness - essentially a high pitched sound emitted which bounces off objects which helps bats identify the location, shape, density, etc of the object. A guy blind since age 1, uses tongue clicking to the same purpose, so much so, that he is now teaching others to use this just as effectively. one of the guys could identify a shape of a tree, and another could navigate his way through a parking lot and into a mall to find a particular store. And, get this, this was the first time he visited the mall. they also go on dirt biking trips. awesome, awesome, AWESOME!!!
