This episode picks up where last week's left off — not questioning the "probable CTE" label itself, but asking what to do given the uncertainty around it. We dig into why a child's developing brain (myelination, the hippocampus) may respond to repeated heading differently than an adult's, then lay out the strongest evidence for restricting heading in kids under 12, including real-world results from youth hockey's body-checking bans. We give equal time to the case for caution, including genuine peer-reviewed findings that complicate the picture. We also break down an angle rarely covered: the physics of the ball itself, using a Guinness World Record Premier League shot to show why "the ball got lighter" doesn't necessarily mean heading got safer. Finally, we look at what happens when rule changes are actually tried, and the kind of resistance to change that has nothing to do with the science at all.
