"Teen rewriting history? Cooper Lutkenhaus is just 17 and already breaking records in the 800 meters. He holds the world record for runners under 18 and recently beat Olympic champion Emanuel Wanyoni. Last year he was the youngest American to qualify for the World Outdoor Championships and now has a pro deal with Nike. At this year's Pre-Fontaine Classic, Lutkenhaus is set to race against top runners while still living a normal high school life. Should this concern us? Share this!"
