Meet Rex. He’s not a real person, just to be clear, if those metal parts of his body aren’t enough for clues. Rex is being billed as the first complete “bionic man” in the world. He stands 6 feet 5 inches and has a head with a face. However, that’s not what’s impressive about this $1 million science experiment. You see, Rex has an artificial blood circulation system (with synthetic blood that acts like normal blood would) and functioning artificial kidney, trachea, spleen and pancreas.
