Paintball party with a side of bruises

With age comes daring acts, I guess. Justin is now almost 10 (April 24) and has become immune to harm, or at least this is what he thinks. He recently attended a paintball party for a friend's 10th birthday. Normally, when he plays he is equipped with body armor, mask, and several layers of clothes, however the paintball park did not provide the kids with any protection except the mask. Needless to say, many kids walked (or limped) away with bruises, scratches, and huge smiles!

What is next?
