A Brazilian told me I hate Brazilians and am the most offensive person he'd ever spoken too.
Where is old Sporty Spice anyways?
But yeah as far as training goes, you've have more options, facilities and just overall comfort and safety in America than Brazil for sure. Honestly if you want to be the best fighter ever, as in complete in every area of the game, you want to be in America training. I find irony in saying this because of how many legends, almost a majority, didn't do that in America...but in most instances you look through their gym and they were the only standout.
But just on
's point, I'm not sure that it's specifically a case of fighters being tougher or harder if they grew up in rough conditions, I think it's more of a case of people needing something to validate their toughness. If you watch TUF, EVERYONE has a sob story. EVERYONE had the "hardest upbringing ever". In actuality, it's probably been pretty easy for them. But they need validation of their ability to overcome and succeed, so they zone in on that. Like that Fedor quote, when they are tired, in the cage or the gym, they need to feel something to push them through and for a lot, that's the idea that "it's taken me so much to get here, I've overcame so much".
For some people, they've been able to build that mentality alone. They don't need the sob story and poor me background, they just have it in them to overcome. They use the fear of losing as their motivation and their desire to win. They don't need to convince themselves they are "doing it for their family" because no fighter in history was doing that.
