Researcher Bertolt Meyer, a lifelong user of prosthetic technology and the model for "Rex", the world's first "bionic man", poses with the humanoid during a photo call at the Science Museum in London on February 5, 2013. The 640,000 GBP (1 million US dollars) bionic has a distinctly human shape and boasts prosthetic limbs, a functional artificial blood circulatory system complete with artificial blood, as well as an artificial pancreas, kidney, spleen and trachea. Rex will be displayed at the Science Museum from February 7. ANDREW COWIE/AFP/Getty Images
