I personally came from the mindset of "never give up, no matter what". I'm sure you can imagine the horror stories I've faced...
Yes, people were very impressed with my toughness and pain tolerance, but being sidelined for several months due to my OWN stupid pride gave me a lot of time to think about how unproductive and dangerous (in the long-term) this kind of thinking really is.
The above point has already been discussed on this thread so I don't really need to add much about it. What I want to share instead is a recent training story regarding chokes and the possible dangers.
A couple of weeks ago I was grappling with a strong, tough guy who's close to my level, so our matches are always difficult. He was in my guard and I locked a guillotine on him. I had it sunk powerfully and there was no way for him to escape. He kept trying to fight it anyway. Eventually he raised his hand as if to tap but didn't tap right away, so I kept the pressure on.
He started to make choking sounds, but this isn't uncommon when trying to fight the choke so I continued to wait for the tap. Once he finally tapped out I immediately let go. He continued to choke and gasp for air. Everyone quickly realized something was very wrong. We asked him several times if he was ok, but he was unable to respond. He was clearly in agony, but we didn't know what the problem was.
We sat him up straight and his face began turning bluish. He was suffering badly and we weren't sure what to do. Remembering my CPR training, I laid him flat on the ground and raised his head, to clear his air passage. One of the guys was about to run and call 911 and I was about to perform CPR when suddenly he started taking in huge gulps of air. He was finally able to breathe again and his face started returning to its original colour. I gave him some water and monitored him for a while longer.
When he was eventually able to talk, he said his throat had been closed and he wasn't able to breathe in or out. I've heard of this sort of thing happening, but very rarely. He took a break, but was able to resume light grappling afterward and seemed fine. It was a very scary situation and I don't know what I would've done if he hadn't made it...
Matt has already laid out my point, so I'll repeat it here for reference because it really bears listening and understanding to:
"Being choked out risks potential injury. There is a small percentage of people which can go into seizure, and there is always potential for brain damage. It's not helpful technically, it doesn't make you any "tougher", and it serves no functional purpose."
And also from Matt:
"Same holds true for a choke. . .yes, it's important to learn to relax, and understand how much time you have to escape. All BJJ'rs learn this important lesson in time.
But once the rear naked is fully locked on, and you realize their is no escape, not tapping, or not honoring a tap, has once again crossed the line that seperates intelligent-tough training, and absolute stupidity."
These axioms are especially true for high-level grapplers and cocky guys. Believe me, I know tapping out "sucks" but not tapping out can suck WAY worse. Let's avoid becoming the next "horrible mishap".
