One way of dividing people up is their opinion of professional boxing. There are those who regard it as both barbaric and dangerous and a second group who enjoy the sport providing it is properly regulated with especial regard for the health of the boxers.  Finally there are those for whom it is just too tame. The members of this third group are most likely to be avid followers of UFC.

UFC is the Ultimate Fighting Championship. It has its origins in the Brazilian full contact sport of Vale Tudo, the UFC started in the USA with very few rules in 1993, and was promoted as a competition to determine the most effective martial art for unarmed combat situations.
