Concussions and brain injuries have been a specter haunting our enjoyment of sport, imparting lasting damage on the lives of many who play football, soccer, and other sports. Virginia Tech has been one of the leaders in testing football helmets for safety, and their research has led to teams across the country changing their helmets for ones that rate better. When they first did their research, they found that half of the Virginia Tech football team was wearing helmets that offered barely any protection from impacts and concussions; since then, they have changed their helmets to ones that rate five out of five stars on Virginia Tech’s STAR system.
