I don’t justify the things Muhammad Ali did outside of the ring by this post but you really don’t know what joy this man had in his life by doing the charity work and philanthropy that had little to do with boxing, Parkinson’s aside.

My point is about beating people's brains out, the objective in boxing. Ali took some tremendous shots. People have different recovery capabilities, the brain is still mysterious, and charities supported aside, the sport should be considered a culprit in seriously injuring him.

From Wikipedia about the causes of Parkinsons (my bold/italicized added):

A number of environmental factors have been associated with an increased risk of Parkinson's including: pesticide exposure, head injuries, and living in the country or farming.[32][33] Rural environments and the drinking of well water may be risks as they are indirect measures of exposure to pesticides.[34][35]
