Sensei Fumio Demura, the persona Pat Morita took on for "The Karate Kid," couldn't fold a single crane. But over time, he worked hard to fold over 5,000 cranes as a part of recovering from great adversity. Fumio was key to bringing karate to the U.S. and then spreading it worldwide. But in recent years, he's been teaching persistence after suffering a subdural hematoma nine years ago, leaving him incapacitated. While dealing with many physical ailments, Sensei Fumio had the time to work on his motor skills through a favorite pastime, origami.
