He Survived Both Hiroshima and Nagasaki

On August 6th, 1945, the US military dropped an atomic bomb on the city of Hiroshima, Japan, and killed 70,000 people. Another 70,000 would die later from injuries and radiation within a few weeks. Three days later, another bomb was dropped on Nagasaki. The Japanese, not knowing how many bombs the US had (which was two), surrendered and ended World War II.     

Tsutomu Yamaguchi was in Hiroshima when the first bomb detonated. He was severely injured, but managed to get back to his home in Nagasaki and go to his job just in time for the second bomb to be dropped. What are the odds? Weird History tells the story of Tsutomu Yamaguchi, who survived both bombs and became a staunch advocate for nuclear disarmament later in life. There's a skippable promotional break from 2:03 to 3:13. 

Speaking of the odds, back in 2012, Neatorama published an article about the approximately 165 people who fled Hiroshima after the bombing and went to Nagasaki for safety. Read about these nijyuu hibakusha, or "double bomb-affected people" in The Unluckiest Train Ride.
