Tua Tagovailoa’s Impossible Choice – The Atlantic

Miami Dolphins quarterback Tua Tagovailoa has suffered his fourth concussion in five years, sparking calls for his retirement. Although it is unclear what risks he faces if he continues to play, repeated concussions can cause memory loss, depression, and chronic traumatic encephalopathy. Experts struggle to predict long-term damage as some players tolerate many concussions with quick recovery times, and the severity and frequency of symptoms may be a better predictor of future cognitive decline.
