I believe that youth sports have become too intense. Many kids today play extracurricular sports starting at a young age, exposing them to athletic injuries. Youth sports include soccer, basketball, lacrosse, and even wrestling. Those sports are only examples of the sports available to kids today. Sports can cause minor and major injuries, and although it is called "youth" sports, the rules are still the same. Competitiveness can lead to kids accidentally injuring each other. The intenseness of youth sports can also burn out the passion and motivation for the sport, as it is too stressful for some kids. In fact, 7 out of 10 kids who play organized sports quit by age 13, according to the National Alliance for Youth Sports. Youth sports have become too intense as it may be too stressful for children and can cause injuries.
