Bit extreme of a reaction to two severely flawed click-bait studies and relevant to that "fear as a product" article from yesterday.

Washington Post: 14 men participating in the study. Each was asked to perform a rotational header — redirecting the soccer ball — 20 consecutive times during 10-minute sessions.

tiny sample size + 20 consecutive headers in 10 minutes is astronomically rare occurrence in soccer, 3 headers in 10 minutes is incredibly rare. Even with this methodology they report *the alterations appeared to clear within 24 hours.

CNN: "Concussions in soccer mostly occur from player-to-player and player-to-ground contact. Heading is involved in only 15% to 25% of concussions in soccer, and most of those are a result of poorly executed headers where two players hit heads,"

So most concussions are from bumping heads, which is a possibility in any contact sport.
