boxing better he would make mandatory CAT scans before fights. It is said that American football player Chris Henry had a good deal of brain damage even before his death at the age of 26. If football players at that age are known to have that much damage, imagine what damage boxers have considering they've taken direct blows to the head since they were teens. A guy on performance enhancing drugs is bad but a guy going in there who is close to being a vegetable is far worse.
People like to condemn boxing as the major braindeadery sport but make no mistake dude, dementia from football is incredibly common. The amount of force in an american football hit is incredible, way more than even the hardest thrown haymaker.
21 out of the 22 players on the field are supposed to be blasting someone else every play. In reality it works out to about 17 players out of the 22, but still a ton and it happens 100 times a game, give or take. So usually that 1 player not blasting is the QB.
They arleady have neurological tests that fighters have to pass during pre fight exams. These include CAT scans I believe.
