This guy has got to be the 'King of Badassery!'

http://en.wikipedia.org/wiki/Tsutomu_Yamaguchi

Not only he survives both the bombings of Hiroshima and Nagasaki, he goes to work merely after two days of the first bomb, and he gets bombed again. In spite of this, he leads a healthy life for the most part, and dies at the age of 93.
