American football experience with multiples; ring your bell... ah just shake it off and get back in there after a few plays.
CTE, brain diseases can start sooner if tackle football is played before age 12

"“Youth exposure to repetitive head impacts in tackle football may reduce one’s resiliency to brain diseases later in life, including, but not limited to, CTE,” Ann McKee, the director of Boston University’s CTE Center and an author of the study,
told the Washington Post. “It makes common sense that children, whose brains are rapidly developing, should not be hitting their heads hundreds of times per season.”
This just came out on this week, based on my on experiences & research I did some years ago we are glad our son stuck with he NFL flag league until he reached high school age. He was recruited big time to play HS football but hasn't played yet, was taking about in his senior year after college commitments.
I don't remember the players name but when my son first started academy he meet a 1st team player who was retired due to concussion syndrome. Kind of scary I recall but my son kind of brushed it off saying maybe he was just too old but that changed for him when one of his friends & teammate actually had to take almost six months off soccer when he was a freshman due to concussion syndrome; he was irritable, getting ringing in the ears, headaches, had trouble with concentration & grades. He liked to head the ball like but son and got hit in the ear & head defending the ball one two many times and he was basically out and hasn't yet returned to the form he once had, but he did recover but sticks to non contact sports for the most part.
The new rules about heading for the younger's might be controversial, but based on new research and knowing what I know now I think I would have been better for him not to start heading the ball when he was like 6, by the time he reached HS he had already been heading for like 8+ years and that's a lot of hits over the years of practices, games, tournaments, etc. My 2 cents.
