Big headache

Studies have recently showed that high school football players can have significant brain damage after playing just a single season.  The crazy thing is that kids can have brain injuries without having any symptoms of concussions.  These injuries are not visible to the naked eye so they are very hard to detect.  Studies have also observed that about two thirds of head injuries occur during practices rather than games.  This could happen because the lack of athletic trainers that are present during practices.  Athletic trainers are trained to pick out athletes that might have signs or symptoms of concussions or other injuries.  Practices also seem to be more physical and longer than the typical football game that occurs once a week.  Coming from a current high school football player I have noticed that practices are usually more tough on the players than games.  We do drills after drills and wee keep doing them till we get them right.  Many of these football drills involve full on contact with another player multiple times.
