What separates British Jiu Jitsu from other self-defense systems?

Most students of martial arts and self-defense systems rely on techniques learned over an extensive amount of time that are static in nature. They learn if a person attacks one way, here is the counter-act to that movement. Teaching someone a technique in itself will be of use to people in defending themselves, provided they are attacked in the very same way they knowingly learned to apply this technique. The truth is we don’t live in a perfect world and if a violent situation arises, unfortunately we will never know what to expect, as the variables are numerous. British Jiu-Jitsu is a principle reality-based system and it is dynamic in nature. It is based on sound principles of leverage and autonomics. The techniques taught are used to demonstrate an application of the principles that take advantage of weaknesses in the human body including the central nervous system. These principles allow a person to be flexible while providing a physical and a psychological tactical advantage while having the confidence to diffuse a potentially harmful situation regardless of age, sex, strength, or body composition
