This year a man named Mark Stark invented a solution to arm amputees. His invention was a mechanical hand that has a cord attached to a socket at the shoulder of the amputee's arm. The hand allows the person to grip a wine glass or even to throw and catch a ball. Most of the abilities are from practice but the amputee still has the capability. Though the prosthetic hand is not the same as the amputee's original hand it is a very big step. This is an important invention, I think, because it gives people second chances to relive what they once took for granted.
