Answer:
I believe health is wealth because is you don't have good health and your living bad then you won't be able to have actual wealth(meaning money). You'll be living and doctors bills and all of that type of stuff. So when your healthy stay healthy don't do anything that can harm your body.
For one, when playing sports you learn teamwork. It teaches you how to build trust and faith in your team mates as well as learn how to function with multiple people in one place. It also teaches communication. When playing sports you have to be able to communicate with your team and coaches or else you will all be lost. When making a game plan it teaches you leadership and how to take initiative.
Hope this helps :)
