In case you haven't been following closely you can add European football (Soccer) âš½ï¸ to the list of sports causing brain injury. "Heading" is the culprit there. Of course there is the infamous "beanball" in Baseball. 🥎
You can add volleyball to the list.
I recently read about a college volleyballer who, after only two hits, has claimed that she suffers from an assortment of issues.
I never realized that a volleyball was that hard.
