So i was at Chipotle with my friend Tylor McCallumore, and we were randomly thinking about who is the Youngest person to ever Win a World Title?! 
I thought it was maybe Yuuki Spencer? (2002) or Takeshi Matsurra? maybe John Narum?
I asked John Narum and he said he was 11 when he won, and said Hajime Miura was the same age when he won.
Can Anybody confirm? plz?!
ty!!!
