(this is civics) Question: Should teens be allowed to play dangerous sports?

Medical research shows a rise in concussions and head injuries in sports like football, wrestling, and hockey. (Soccer, gymnastics, and cheerleading have been criticized for unsafe conditions, too.) Some say such sports should be banned because they cause damage to the brain. Some say new safety regulations are needed. Some say the sports are fine the way they are. What do you think?

what is the claim and the counterclaim of this?
