text: Kids work really hard to put forth effort on school work,homework, and participate in school projects. That can be already enough stress on a kid no matter what age. When having to put another thing on top of school work managing time for sports, and extra activities sometimes kids just cant deal with it. Grades and having a good GPA can come first for some kids. Sports and other things come last. You could probrobaly already have something after school you do and having to move your whole schedule around can be really tiring and stressful.
