Study estimates 75% of NFL players who died over 15-year span had CTE

What HN thinks

A room full of former linemen and worried parents agreeing that heads are for thinking, then arguing about whether shinty is scarier than hockey.

Keep kids out of tackle football
Many commenters, including ex-players, say they won't let their children play because head impacts are cumulative and most damage happens before the NFL, at youth, high school and college levels.
Other sports carry risk too
Some argue soccer, hockey, rugby, boxing and skiing also cause brain injuries and football is simply the most studied; others reply that football is uniquely bad because collisions are built into every play.
Change the rules, not the sport
Proposals include moving to flag football for kids, banning contact in practice, redesigning the line of scrimmage, stricter targeting enforcement, or even removing pads; skeptics say that would no longer be football.

Consensus: Most agree repeated sub-concussive hits accumulate and make tackle football a serious brain-health risk, especially for kids, though they note the study's sample is biased toward symptomatic donors.
