Importance of Physical Fitness

There are many reasons why I believe physical fitness is important. I'm sure if we all listed reasons, we could come up with quite a list; however, I want to narrow the list to what I believe is the most important. Below is my list of four:
-Increase self-esteem and capacity for learning.
-Help kids handle stress.
-Build and maintain healthy bones, muscles and joints.
-Help control weight.
