What were the most popular sports and why?

Think about the sports you have participated in as a youth. What were the most popular sports and why? At what age did you start playing and why did you begin then? Did you stop playing and why? At what age did you stop playing?If you never played in sports, tell why you never played in sports and talk to someone who did play as a child and ask them the questions listed.How would you initiate getting children involved in sports? What programs have you seen that are successful and what have they done?I grew up playing baseball and football. All my friends played those sports so I did as well. I stopped playing football after my ACL surgery in 2013 and I still play competitive baseball till this day.
