I would host a competition that measured strength, speed, agility, endurance, and intelligence. I would measure strength using some strongman and some powerlifting lifts. I would measure speed with 100 meter sprints. I would measure agility with some kind of ropes course, obstacle course, and gymnastics meet. I would measure endurance with a triathalon plus rowing (a quadrathalon?). I would measure intelligence by testing ability to memorize a bit of text in their mother language, teaching them the rules to a made-up game (Calvinball anyone?), and testing them on some trivia game with a format like Jeopardy. What would you measure, and how would you measure it?
