# bio (long form, separated for readability)
bio: |
  Born Choi Yeong-eui on 27 July 1923, he carried a Korean name into a Japanese art and remade both. He founded Kyokushin Karate, stripping away the ceremonial distance and insisting students hit for real. It became the first full-contact style that mattered, the one every other hard school had to reckon with. He died 26 April 1994, but the bruises are still standard issue.
