Soccer is the most participated sport in elementary school because its easy to learn and no one gets hurt. When they hit middle school almost 75% of the kids drop out. Why? Because they figured out they are not that good and running around chasing a ball is no longer fun.
It use to be baseball was king in elementary school but now when little Johnny gets hit with a pitched baseball its all of a sudden not fun anymore.
Football? Very few kids try that more than one year. Again, people are hitting you and it can sometimes hurt.
Look for tetherball championships soon.
The true sign of intelligence is not knowledge but imagination.
