I actually don't mind the UFC especially back in the days when anyone could fight anyone,no weight restrictions,gloves etc.When Royce Gracie was the man to beat,what a fighter.
I couldn't watch the second and third videos as I can't be arsed signing in to prove my age.
I much prefer boxing though,IMHO its much more of a skilled sport,having to stand for 12 full rounds toe to toe,there's no time to arse about hugging on the floor,no breathers.
I actually have a perfect amateur record,I got my license then fought 0 times
