Hunt probably has three fights left in his career after this one - he signed a new six-fight deal with the UFC in April last year - but the old warrior who has been fighting all his life one way or another is likely to be defiant until the end.
"I feel like I could fight for ever, but it's hard training the body," Hunt told the Herald. "The mind's all right but not the body. Who knows? We'll see.
"There is a lot of talk about that - 'you're too old' or 'too fat'.
"I still feel I'm the best. I asked the guys [in camp after the Overeem defeat], 'was I outclassed out there? I don't think so'. The guys said, 'it was a pretty even fight up until you got caught'. If he was beating me up, then my thought processes would be 'maybe the game has changed ... and it has got the best of me'. But I thought it was a pretty good competition up until I got caught."
The Sydney-based Hunt, the boy from South Auckland who endured a hellish childhood, including frequent beatings from his father as described in his autobiography Born to Fight, continued on his theme when saying he had been knocked out only three times in his UFC career. There remains bitterness about how some of his opponents have tested positive for performance-enhancing drugs, but his fighting spirit remains undimmed.
"All those guys who say 'quit, give it up', they don't know what they're talking about. I don't even listen to their rubbish. They can say whatever they like. We're talking about the elite fighters of the world.
"A lot of the fighters I have fought have been younger than me; younger and bigger. But I've still beaten them. I still have the dream of being the best MMA fighter in the world and that's what I'm still chasing."
Asked about his memories of his last fight in New Zealand in 2001, Hunt said: "The last time I fought there, I was out partying till 2am and I lost on points to Peter Graham. I made a lot of errors in my career."
