Here's how I look at it. I've been choked unconscious before. For the sake of argument say it takes exactly ten seconds for me to be put out. I remember the first time getting choked out the sense of panic I felt. You go through this "death rattle" before you are out cold. When you get close to be choked out you feel this same sense of panic and want to get out or tap as quickly as possible. As the years go by you get use to it. You don't panic. Often just by being relaxed and not panicking you can manage to escape or have your opponent release because he doesn't think he has it. But this not change the end result that after ten seconds in a legit carotid choke you are going out. I specify carotid choke because it's cutting off blood flow to the brain and not the type of choke that cuts oxygen to your lungs. You can train yourself to hold your breath longer.
So, as by way of comparison, if it takes X amount of foot pounds getting hit on the button to put you out you are not going to be able to change that. You will be far, far more desensitize to being hit than the average schmoe out there where just a tap on the face sends them into a state of panic and confusion, but a knock out punch will still always be a knock out punch. In fact, I would argue that as the years go by your knock out tolerance goes down. Years of getting pounded doesn't necessarily toughen you up but may in fact "soften" you up. Again, pure speculation on my part but you just see it all the time as fighters age. Wanderlie Silva is really not that old. I think he is maybe 2-3 years older than Leben but I've seen him take some lethal shots and still keep coming like a rabid dog. But the guy has been fighting and taken shots forever. He was going through the brutal Vale Tudo ringer long before he got into Pride and UFC and those guys were fighting every month. Same with guys like Nog and Shogun. They are still in their 30s but they just seem war torn. Shogun was in Pride I think at 21 and was already champ at 23. Rogan once commented that you have only so many shots that one can take in a career before you just can't take those shots any more. I know from my experience personally, I cannot take falls like I use to. I completely avoid it now in training. It's not like the years of being dumped on the mat has toughened me up. It's just the opposite. It's like my body is more of a China doll that shatters on impact.
Wow!! so you are a real "Jiujiteiro" apaga mas nao bate. I'm glad to know that you have the spirit.
And people say that Jones would have a chance against Shogun during his prime... Shogun,Wanderley and Nog their bodies can not take hits anymore...Shogun has tons of injuries.
Age+injuries+surgeries = you are F*cked.
F*ck can you hear the sound of this punch?
For the Shogun haters and Jones lovers... look at Shogun's fight history and tell me.
How many fighters in the list Jones could submit/KO?
