CHINESE farmer Sun Jifa, whose arms were blown off in a freak explosion, has built himself bionic arms as he could not afford the pricey hospital ones. The 51-year-old lost both his hands when a bomb he was making for some blast fishing detonated prematurely, but could not afford to shell out for the prosthetic arms the hospital offered him, instead coming up with his own handy solution. Sun spent eight years creating the prototype for his own metal hands, which function using a series of wires and pulleys inside the shell, allowing him to grip and hold objects.                                   –Metro
