I read this article this morning, and it sounded too good to be true. Then, I watched the video (ended up watching the whole thing) and my jaw hit the floor. This one guy, after having a bad spinal injury, spent years researching and eventually testing a procedure on himself. Now, the company he has founded has had great success testing with monkeys. They were able to run mere weeks after having their spinal cord injured. Wow.

If everything is as stated, then this is incredible.
