i actually no a little on dim mak be cause it comes up in my chin na and tai chi books....and because kun tao is a deadly style of fighting wich incorporate internal and external techniques making it a balanced style....people fail to realize what dim mak truely is....the way you body works flow, and even strive to exist...your body works to obtain its balance....by breaking the balance you can cause harm to a person....by hitting certain points: swelling organ or vital arteries and veins or vital point of a person body you can cause extreme amounts of damage.If someono damages an organ in your body it fails in turn it will poison your body in then in time even die or shut your body down....snake style for instance in fast and acurate and very deadly it might not be called dim mak but it executes some of the same concepts of dim mak. snake style blinds,poisons,knocks out, and even more entense things can happen to a person when use this style.....many people ask stupid such as "is dim mak real?" have they sat down and read a book on dim mak ...have ever in your life of martial arts studied some pressure points...or even the nervevous system...if i can hit person in certain place and make lungs stop, or knock some body out what do you think a more deadly strike would do to a person...most styles of martials have techniques that cause extreme amounts of damage or kill people. nowadays it just a matter if its taught.....accupunture and acupressure can be use in more ways than it should...
