The tongue is not only good for tasting food, but it is extremely versatile by remaining active despite the rest of the body suffering from massive trauma or disease. This makes the tongue an essential body part to consider when it comes to developing wheelchair controllers and other communications device. A group of students at Georgia Tech has successfully worked on a new system that relies on the tongue and several embedded magnets that enable quadriplegics to control multiple devices simply by flicking their tongues. Since the tongue is more agile than your average Olympian (I'm stretching the truth here, but do bear with me as I try to illustrate this point), it makes for a suitable candidate to suit this new control system.

It will make everyone great at kissing and oral sex too.
