For many, American football is a beautiful game that is simple to enjoy but complex to master. Choreographed with a mixture of artistry and brutality, it features the occasional “big hit” or bone-jarring tackle, forcing a fumble and turning the tide of the game.

But with this part of football comes justified concern about the long-term health effects of engaging in this type of activity over time, concerns that abound in practically every high-impact contact sport.

It is possible that effects of continued involvement may accumulate quietly in the background until they show themselves, later in life.
