I've amazed that prizefighting, both Boxing and Mixed Martial Arts, are legal at all in any civilized nation.

It's legalized assault, perpetrated in front of millions of screaming eye witnesses.
Many viewers have been witness to the televised beating that killed a man or maimed them for life.
For the fighters who avoid that kind of tragedy, their damage manifests itself down the road in middle age with neurological damage, post-concussion syndrome, early onset Alzheimers disease, parkinsons, kidney failure, depression... and with 95% of Boxers never having made any serious money for their damaged bodies and minds.

But money talks in a capitalist society.
Worldwide, the people demand combat-sports, and fighters make their choice to risk their health and life every time they get in the ring.

Boxing is a global sport with about 20 thousand pro fights each year. God only knows how many amateur bouts each year. At the London 2012 Olympics, 79 countries sent Boxing teams; Boxing will NEVER be banned everywhere. The same does not apply to MMA though.

Y'know just last week, the concussion law suit against the National Hockey League was all over the news. Originally 10 former NHL players started the suit, but the list has grown to include over 200 former players, all seeking damages for concussion-related health problems, and that the league knowingly put them at risk.

With concussed football players and hockey players suing leagues for hundreds of millions of dollars, what about a business where the whole point is concussions?
