Imagine losing the ability to walk. Imagine losing said ability for over 20 years.

Now, imagine the kind of elation you'd feel if an invention came along that made it possible for you to walk again.

That's exactly how the man in this video felt after using the ReWalk ExoSkeleton robot. Designed by Argo Medical Technologies Ltd., the robot is a lightweight brace device that attaches to your legs and restores a person's mobility functions.

In the video below, you'll see a man stand up from his wheelchair and walk down the aisles of a shopping center without the tiniest hint of struggle.

The device will be available for purchase in late 2011.

Watch the video now - and remember to keep some tissues nearby.
