Human exoskeleton suit helps paralyzed people walk

Israeli paratrooper Radi Kaiof has been paralyzed for the past 20 years. Thanks to a new device called ReWalk he now walks down the street with a dim mechanical hum. That is the sound of an electronic exoskeleton moving the 41-year-old's legs and propelling him forward.
