Tsutomu Yamaguchi was 28 years old when the first atomic bomb was dropped on Hiroshima. He was there on a business trip and survived with serious burns, only to make his way back to his home in Nagasaki just in time for the bomb to be dropped there. The man two atomic bombs couldn't kill died today, at the age of 93.
