'Exoskeleton' Lets Some Paraplegics Walk Again

ReWalk Robotics has built a motorized exoskeleton that gives some people with debilitating spinal injuries the ability to walk, and it's the first such device to receive FDA approval.

Here & Now's Sacha Pfeiffer met a 51-year-old Army veteran who's been in a wheelchair ever since he fell during a welding job who is using the exoskeleton to get around.
