Do concussions cause early death?

In this episode of Stuff You Should Know, Josh and Chuck dive into the surprisingly serious world of concussions, exploring how these "mild" brain injuries are anything but mild. They discuss the symptoms to watch for, why the NFL has finally started taking head injuries more seriously with new rules, and the shocking research showing that multiple concussions can make young athletes' brains look like those of 80-year-old Alzheimer's patients. The hosts also cover proper treatment, debunk some common myths about concussion care, and share some personal (and questionable) stories about head injuries along the way.
