I'm guessing many of you are busy watching the Super Bowl as I write this. On the one hand, I have the game on because tradition, on the other hand, and if you are seriously preparing for the future, warning people away from playing football or allowing their children to play football seems to be the most prudent thing to do.
The fact that 99% of former football players in one study had CTE should have immediately put a stop to the game (but again, tradition is fairly hard to change, and then there is the massive amount of money involved in the game). Also "white flight" is now a thing in football. Apparently word is getting out that whether in football or in rodeo or in other sports where head injuries are common, setting your kids up for brain damage is not a good thing to do. Obviously.
The preparedness aspect of this is pretty straight forward as well--brain injuries are bad. Repeated brain injuries are really bad. While the problems may not show up immediately, they will in the future. Needless to say, the common symptoms of CTE will put a serious damper on your prepping (and your life in general) so while the game is exciting to watch for many and exciting to play for some, putting a halt to things that will obviously injure people may not be popular but it is common sense.
