Martial arts or real world defense?

Personally i feel the Martial arts is debunked it has become more commerical and sport than what it was originally conceived to be these where cultural systems derived for a time of large battlefields and for the weapons of old .Which in their day where the best they had and they were evolving ,i can say this i have studied Martial arts for pretty much of my life from my shoalin  to judo to kenpo which i studied for many a years and from basic hand to hand in the marine corps to line training, of all the dozens of actual real life fights and my experiences in fighting all the training in the Martial arts don't help if the other guy is in a wining mindset there is nothing to stop him from absolutely kicking your ass, so you have to be willing to sacrifice your body take a hit to get in and make that vital hit or hits if you can get more in go ahead and do so! You must know collapse knowing when the opponent has last his momentum in his attack and if you can recognize his collapse you can crash in and Finnish him off, Martial arts give you discipline ,yes but unless your able to practice 12 hours a day and get to use techniques in full speed on various different body types many of them wont work on most people! Unless your are a great set-up artist, basic techniques is what you need and work on them till you have them right you must tailor your self to your self-defense not everyone can deliver high kicks or those fancy jumping spin kicks not all your fighting will be in a gi! but in street clothes or uniform which ever it maybe, your fighting is not coreaghrafted or the same every time. There are precursors to fights telegraphs that a person is giving so you should be aware of these ,I am not condoning fighting but should you have too, be mean don't feel sorry for the other guy because i am sure they wont about you so give it to em,head butts groin kick,grabs,clawing eye gouging ,biting,weapons of opportunity if your going to go against an weapon you best defense is to get away but if your cornered with no alternative by all means fight protect yourself ! Legally you can one up the threat that has been presented. Be careful of lethal force, if you should have to escalate and it does become life or death by hell sometimes it better to reap what you sow and be alive i will be discussing this topic in further chapters as stuff comes into my mind ... to be continued
