I trained martial arts for close to 20 years, and half of that time as an instructor. I have been through Judo, Sambo, Tae Kwon-Do, Kickboxing, Hapkido and some other variants (like full-contact Tai Chi of all things, hehe). Here's my take...
Top MMA practitioners like Sebastiaan Rutten and Anderson Silva have black belts in Tae Kwon-Do... so one could think that they are McDojo - only evolved... but, take Lyoto Machida - unbeaten and very smart with a mix of BJJ and traditional Karate... Also the number one icon of MMA - Fedor Emelianeko - a combat Sambo practitioner, and that's all he does - no other styles.
So, my experience training as well as going through many instruction courses and personally knowing some MMA fighters - e.g Gleison Tibau who lost to Joe Stevenson at UFC 86 - is that...
it is all about the person who fights - not their "style".
So many people have all kind of distractions on their mind when going to fight, as well as not having the proper mindset. Any decent martial artist from any style - except stuff like Tae Boe - can potentially kick your ass. I have friends who are powerlifters - from my home town, and some of them are European champions, world champions and regional champions; and a training partner of mine from Tae Kwon-Do is now a world strong man competitor as well.
TKD is efficient at longer distance to medium distance, and useless up close. Judo, Sambo, BJJ, wrestling is great up close. Boxing is great at short distance, Kickboxing at short and medium distance. For someone who knows how to use techniques and have the right mindset - they can be efficient against normal people, even other martial artists. When I worked as a bouncer, I had to disarm a crazy guest drawing a gun to shoot the police - and in situations like that you better know how to be street smart than anything else. Being able to effectively communicate with people is way better than knowing how to punch their lights out...
MMA is different than a street situation, primarily because you don't fight naked with other guys - unless you really are in a shit load of trouble, with YOU being the winner's prize...
It IS all about the persons - not their styles...
If trading needs some changes - it is in the lack of transparency, honesty of the systems - lending to corruption.
Any trade should be flagged as long or short position, as well as having the complete instrument log/position and id of the trader.
The most effective self defence is also one of the most used and popular - running as hell! It beats any "style" hands down...
