The REALITY
Most Martial Arts Systems take years to learn in order to be effective in a Realistic attack
Many martial artist from traditional systems will freeze during a real attack, due to adrenal rush, un-realistic training and techniques, and brain overload due to training in too many unnecessary techniques.
Most martial art classes are only 30-45 minutes long.
Funny embarrasing uniforms and barefeet are often required for students of traditional martial art schools. Again this is unrealistic in the real world.
