if you suspect, or even have a hint of cte, stop fighting. it’s that simple.
i don’t feel bad for pro athletes one bit. even the lower paid athletes make enough to live comfortably for the rest of their lives if they spend and save wisely. they get to do something they love, get recognition and support (sometimes fame), and retire early. debilitating injuries can happen, but that’s a risk they’re all aware of beforehand, and the vast majority don’t have them. you can get injured in almost any industry btw, so that’s not unique to athletes.
