Supposedly some people are more prone to dementia related to repeated blows to the head that others. Hopefully through testing they can determine what causes this and develop tests to let athletes that may have trouble later on retire before they do too much damage. A good example of this is Jerry Quarry a heavyweight contender from the 70's who died in the late 90's of dementia at the age of 53, his last few years he could not even dress himself. On the other hand Joe Frazier another well known heavyweight from the 70's a former champion who basically blocked punches with his face has no dementia, and still is active training fighters at the age of 67.
