Someone from grade school before had his legs almost amputated because of a freak accident. The accident took his calves on his legs and left him limp. He needs a muscle builder to help him restore the muscle he lost and to get him to walk straight again.
I remember that he used to be heckled because of it. The robot, he was called, because he walked like one with his metal strips and all. I saw him in a social networking site and I am glad to say that he got his legs back and is now happily married with two kids.
