Jose Aldo's pro MMA career began over 11 years ago.
After 26 fights, he has only once suffered defeat. That came 10 years and 19 fights ago.
A career in the sport is obviously incredible attritional on an indivudal's body. The get in, get paid, get out as quickly as possible mentality is one we've heard Conor McGregor preach often.
At 29, McGregor's opponent in this weekend's UFC featherweight unification bout could be about to hang up his gloves.
Speaking to MMAPlus.co.uk, Aldo's training partner Andy Souwer, a Dutch kickboxer, told of his belief that this is likely the last time we will see the Brazilian in the octagon - win or lose.
To be honest, I think yeah. I think so.
I think he's done with it. And ready. I will agree.
Whatever his thinking, or his decision, it will be good for him.
Souwer still belives Aldo has enough to 'put McGregor to sleep'.
Of course, man. Jose Aldo is the best pound-for-pound fighter in this weight division. He will succeed this time also. It would be a fairytale story, of course.
But I will go for it. I would put my money on it.
Given that this could be Aldo's final MMA fight - win or lose, as Souwer agreed - you would have to wonder what his mentality is going into the fight.
Does he see himself as incapable of continuing in MMA? And if so, is this fight simply being viewed as one final pay day?
