I think its rare to get brain damage from fighting. The only person I know is Muhammad Ali..
Soon you would prefer Xbox matches only. We have all gone soft. These matches have rules to limit damage, and the fitness involved requires them to be healthy athletes.
MMA events are safer than the stupid fake wrestling like WWE. When people are injured in sports, they are not surprised, they understand the odds. People who die running with the bulls are old enough to accept that risk.
Why cry over people choosing to do what they do? If people get hurt, it isn't you, so relax. Stop trying to limit the things you have no experience with.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
