(Our happy hour fact to amaze your drinking buddies with.)

An Israeli engineer has developed an electronic exoskeleton which will allow those paralyzed from the waist down to walk upright.

Users set the system to either stand, sit, walk, descend or climb and then body sensors take over to guide the robotic legs into motion. The invention is the brainchild of Amit Goffer, a victim of paralysis who unfortunately can't use the system because he doesn't have fully functioning arms.

The product should hit the commercial market by 2010 and will retail for around $20,000 dollars -- about as much as a high-end wheelchair.

If there's any justice in the world, an upgrade is already in the works that Goffer can operate, or, at the very least, he will make enough profit from the invention to hire a young, busty caretaker.
