His opponent Frank Mir has threatened to end his career.
But Australia-based Mark Hunt reckoned the stakes are much higher in Sunday's crunch UFC heavyweight bout in Brisbane.
"I am ready to give my life in there - I am not sure whether he is," said Hunt of former two-time world champion Mir.
"That's the only way to feel if you want to become the best fighter on the planet.
"I am willing to go that much further than he is."
At 41, New Zealand-born Hunt admits he is closer to the end of his career than the start.
He is the oldest heavyweight and second oldest active UFC fighter in any division.
He had to lose 20kg just to make weight for this weekend's bout.
But Hunt - dubbed the "Super Samoan" - says he is not finished with yet.
Especially with Sunday's victor set to keep alive their chances of another title shot by earning a spot in the top 10 official rankings.
And few would argue with Hunt after witnessing his last bout.
Hunt (11-10 record) enjoyed a first-round knockout of Antonio "Big Foot" Silva in Melbourne last November, the eighth KO of his career.
It was a re-match of their bloody draw in 2013 - the first UFC showpiece bout held in Brisbane which ended in both fighters being taken to hospital.
However, Brazilian jiu-jitsu expert Mir presents a very different challenge to that of big-hitting Brazilian monolith Silva.
Of Mir's 18 professional wins, eight have been by submission using seven different techniques.
It's grappler versus striker.
Or the way Hunt describes it: "His game is to try and put me on the ground and submit me, my game will be to try and knock his face off."
Suffice to say, Hunt was not concerned by Mir's threat that he would "break his legs" before ending the burly Kiwi's career this weekend.
"It's an idle threat," said 118kg Hunt.
Asked if Mir had been disrespectful, Hunt said: "That's his game.
"I will show my respect when I am punching his face in."
