To this day JKD is ever evolving with the new forms and styles
. Many would beg to differ with Brazilian Jujitsu and the Gracie camp, what we see today in Mixed Martial Arts. At the same time, the MMA is more sport with rules confined in a cage. Not that there is anything wrong with MMA or the UFC but in real self-defense situations there is no time to roll around the ground trying to put someone in an arm bar or triangle. In real combat situations, there are no cages that you are confined in with nowhere to run. There are no refs to stop the fight when one person can no longer defend himself or herself. In real life situations, if no weapons are involved Jeet Kune Do training and techniques will help in real combat situation. If there were a weapon in play, if you are not Bruce Lee I would say run, run to the nearest police station. Do not stand in place trying to intimidate your attacker by breaking boards because "boards do not hit back."
