Call me naive, go ahead, but I'm still blown away by what technology is providing people these days. Take the story of a man who lost both legs in the Iraq war. Bluetooth technology is helping him walk using prosthetic legs -- yes the same technology that's revolutionizing hands-free phone calling.

Here's the scoop but take time to read the entire CNN.com story:

<i>Computer chips in each leg send signals to motors in the artificial joints so the knees and ankles move in a coordinated fashion.<p>

Bleill's set of prosthetics have Bluetooth receivers strapped to the ankle area. The Bluetooth device on each leg tells the other leg what it's doing, how it's moving, whether walking, standing or climbing.</i>
