Concussions are serious brain injuries that are caused by a blow to the head or body. They are common in contact sports. Dr. Robert Cantu is a concussion expert. He says tackle football, heading in soccer and bodychecking in ice hockey should not be allowed until kids are 14. "Starting later is fine too," he says.

But other experts think the risk of getting injured is just part of the game. Plus, if kids wear safety gear and play correctly, they will cut down their chances of getting hurt.

NO!

Sports are a great way to be active and to learn about teamwork. But contact sports cause too many injuries. With teams open to a wide age range, things can get unfair. Serious injuries, like concussions, can lead to kids' missing school. Also, contact sports teach kids that violence is okay. Kids should stick to playing safer sports when they are younger than age 14.

YES!

There should not be an age limit for contact sports. If you learn to play a sport the right way at a young age, you will become a better player. Plus, if kids follow rules and wear protective gear, they will not get hurt. Teams can let parents know about potential dangers and what might happen during play. Then each family can decide if the sport is worth the risks.
