Now Nate & his older brother Nick have never been boys who stick to the script and that definitely has something to do with their rough and tough upbringing. What got Nate Diaz into fighting in the first place he wasn't driven by passion for the sport but his literal hunger to survive. When he went and trained with his older brother he would be treated with a burrito afterwards, if he didn't train he didn't eat. He was a brawler in school which resulted in him being put on drugs then his peers were informed that he was given meds and the fighting only escalated. He moved from school to school before dropping out entirely – then more tragedy struck when his childhood sweetheart committed suicide. Ya, he's had it tough – no wonder his signature move is to give the world the double middle finger.
