I kept hearing Ali had Parkinson's. He didn't. He had brain damage from boxing - what used to be called "Puglistica Dementia" - "punch drunk."
Why does the media lie about these things? At the end Joe Frazier could barely talk. Jerry Quarry made it until his early 50s and was about ten years old mentally. The normal fluid-filled spaces in his brain were the size of oranges.
There are former boxers - whose names I cannot remember - who are in nursing homes in their fifties.
Boxers cannot give up the fame and attention, even if it kills them.
