Recently i read a story about how a highschool basketball player Wes Leonard died of a heart condition that was undetectable because of an enlarged heart. He collapsed on the court and died. They said he was 1 of the healthiest one on the team and nobody knew that he had the heart problem. So im kinda scared that will happen to me.
