Chinese farmer who lost both of his arms in a blast fishing accident built himself some new ones! Sun Jifa, 51, decided to construct bionic arms after he could not afford the expensive hospital prosthetics. He spent eight years creating the prototype for the limbs, which function using a series of wires and pulleys inside the metal shell. “I control them with movements from my elbows and I can work, love normally and feed myself just like anyone else,” "I made this from scrap metal for virtually nothing. There is no need to pay hospitals a fortune,' he said.
