Since people were going into the wrong sport that wasn't fit for them, it was decided that your sport will be decided by your family's lineage. Families that had those who have been in the military go into the sports paintball, or airsoft. Others who are tall and good at throwing a basketball go into basketball. Those who have quick reflexes go into either fencing, martial arts, racket sports, soccer, hockey, boxing, or motorsports. Those who have a lot of power or strength go into football, baseball, track, and field, sprint swimming, or kickboxing. Those who have patience go into golf or some other slow-paced sport.
This is the new age of sports.
