newshour:

New research shows kids who play football take hits to the head just as hard as any high school, college or NFL player.

Because they lack the protective neck and chest muscles of older players, young players are kind of like bobblehead dolls - the acceleration of each hit is greatly exaggerated. 

Watch Stone Phillips report on the findings. He also joins us for a live chat tomorrow at 12 p.m. ET.

Stone Phillips is reporting for the Newshour now? Okay then.
