Growing up, Matthew Benedict played football in the fall, hockey in the winter, and lacrosse in the spring. In the summer, he and his brother and their buddies would head to Toronto for weekend hockey tournaments. Each of those sports meant he took hard hits to the head for years. At the age of 26, he took his own life. His story illustrates the challenges parents face as they decide whether to let their sons and daughters play contact sports, as well as deciphering conflicting messages from scientists and sports leagues about head trauma.
