Do Mexican fighters age quicker than other fighters?

[ironalex]

when two mexican fighters fight its not as interesting, which means low ppv sales, like barrera-marquez... its fights like marquez vs pacquiao, barrera vs hamed that get the mexican audience interested...

which is the hightest ppv record between 2 black fighters in recent time?

you should of rephrased this into "black non heavyweights in recent time?" coz theres loads of heavies black and black who sold loads, tbh if your heavy the audience seems to love buying it, thats why another reason mexican v mexicans dont have major sales, because there aint a lot of mexican heavies.
