Fußballkopfbälle können das Gehirn schädigen, bevor sich der Kopf überhaupt bewegt

Looks like an AI summary of https://journals.sagepub.com/doi/10.1177/17543371261438388.

Basically, they made a faux skull, filled it with a brain’esque gel, and fired soccer balls at it. Repeat over 400 times with a variety of balls, including leather and synthetic, the resulting data show that waves of pressure move through the cranial cavity in the nano seconds before the skull ricochets from the impact. While limited by the single skull model, the data have been sent to FIFA in the hopes of making engineering changes to balls to limit brain injuries on the pitch.

I do headers all the time, I wonder how much brain damage I have lol
