text: A lot of students play sports, for their school or a rec team, and having more to pile onto their schedule is stressful. Sports are hard enough as it is, and to add to that also still having to participate in an extra activity can mess up your flow. Having to balance not only one extra thing outside of school, but two, can be very stressful. Too much stress can cause you to possibly mess up on your team, and get kicked off that team.
