That's going to work most of the time, unless someone expects it or has a gun/taser, then you're fucked.
Krav Maga is not a combat art, it's the Israeli army's psychological training for soldiers in urban warfare.
I recall this one incident where my friend had a guy in a headlock and the guy lost consciousness so he couldn't tap out. When he finally let him go the other dude had a seizure there on the spot.
The same friend ended up permanently injuring his back by being slammed into the ground while attempting to perform a flying armbar on his opponent.
If you go out from a chokehold, it's either because your training partner is an asshole and didn't let go (unlikely in my experience), or you were stubborn and refused to tap (more likely). The seizing is typical when coming back from a blood choke - not good, of course, but it's what happens.
Wikipedia has some mention of this: http://en.wikipedia.org/wiki/Boxing_glove#Impact_of_gloves_o...
The striking sports are definitely more of a risk than grappling (also less useful in my opinion). Boxing is probably the most likely to cause long term trauma like hematomas.
LOL at the casual way you say this. Not a criticism, really, it's just waaay outside my experience.
