I personally think it does to some extent, but it's not a disabling effect like the movie says, if the concussion effect is so strong that most players on any winning football team are in their mid-40s and 50s If everyone had a concussion, given the strength of the NFL, the movie would have been blocked long ago. But it is true that the shock effect has raised two thoughts for the audience, one is the relationship between human nature and interests, and the other is the need for revolution and struggle behind respecting the truth.
In fact, such a discovery was indeed made in an authoritative medical journal in the United States in 2008, but it is equally puzzling as to what harm it causes, why it is still not banned, and why the NFL is still there.
