How some ppl avoid cte
There's alot of boxers who when they get around 50 you can just tell something is wrong. They can not put a sentence together. They make Biden look like a grand master chess player. But then you got some boxers who took more damage and they show no signs of damage. Take Holmes and Foreman for example. Both ate bombs their entire career and fougbt into their 50s. Foreman did not have much defense! Yet in his 80s he's witty and he even does commentary for boxing some times and appears to have no issues whatsoever. But then you get guys that took much less damage like Jerry Quarry but are dying from dementia in their late 40s.
I think there is a genetic component that makes you almost immune to CTE.
