Man who survived both A-bombs

Tsutomu Yamaguchi is a 93 year-old Japanese citizen who endured both the Hiroshima and Nagasaki bombings in August 1945. He had been on a business trip in Hiroshima on the 6th, the day the first bomb was dropped. Yamaguchi suffered severe burns and spent a night in the hospital before returning to his hometown of Nagasaki. He lived through the second bomb on the 9th.

I'm sure if there were third and fourth bombs he would have survived them too. Just about the only person to whom Harry couldn't give hell.
