inputs: hypothesis: Yamaguchi survived two atomic bombings. premise: Quite simply, Tsutomu Yamaguchi is one of the luckiest men in the world. This slight 93-year-old with white hair, who is now largely confined to a wheelchair, was formally recognised last week as one of the tiny handful of people to have survived not one but both of the American atomic bombs dropped on the Japanese cities of Hiroshima and Nagasaki in August 1945 - bringing to an end to World War II. Known in Japan as one of the hibakusha - literally 'the explosionaffected people' - Mr Yamaguchi had long been recognised as a survivor of the nuclear explosion in his home town of Nagasaki.
