I get your logic but dude if you are 42 testing yourself to see if you still got it and hey if you do good in the test you’ll keep fighting and not quit and your test proctor is Jon fucking Jones….. Man shut the hell up lol he came for a bag
I would and you would and pretty much any sane person would, but you are forgetting...these are
fighters we're talking about. Worse fighters with worse losing streaks tottering at the end of their careers keep saying they're on their path to the belt. An insane amount of self-confidence is almost mandatory for reaching the higher echelons of the sport.
I don't think it was "if I do well in this test I'll continue." That simply isn't the kind of forethought he goes through. That's the whole point of his "we'll see" statements, precisely because he refuses to think beyond the fight. Not even an either/or possibility. Just...I'll get there when I get there.
And why would he think he needed to test himself, other than a couple of numerals he could laugh off with the old line "Age is just a number?" He felt physically fine, probably better than during a lot of his career what with the rest his body had been getting. With all that work to gain muscle he's probably stronger than he's ever been. No way he wasn't still blasting through his teammates at the gym, he's the only high level guy they've ever produced. His last loss he wrote off as due to not enough mass and a rash mistake when he thought he had his opponent stung, not because of general decline.
========================
There are two things he's said about when he thought he would retire, whenever he was asked by journalists throughout his career:
1. I think about retiring after every fight.
2. I'll stop fighting when it stops being fun.
And there's a third thing that's less known:
3. Long, long ago he talked it through with his coaches and his girlfriend-now-wife, that whatever moment he decided to quit it was fine with them. Like literally he could just stroll up unexpectedly one day and say "I quit," and it would be all good.
So.....
1. it was after the fight where
2. it stopped being fun and
3. he knew it was OK to quit on the spot
....so that's what happened.
