Bigger, younger, stronger thugs who are even trained in BJJ & MMA!! Sometimes 2 or 3 assailants and then there are attackers with "Fervor", facing a vicious, amoral human animal who will not stop until he kills you? Are you ready? Well have no worry for there is a viable soltuion!!
Pekiti-Tirsia is not a sport art but a Tactical Combat Trade taught to Navy Seals, Recon Marines and Special Forces in multiple Nation States. IT INSTILLS THE INSTINCTIVE PERFORMANCE of Tactical Material NOT sport to END THE THREAT.
You will not be meeting bigger, younger assailants "force for force" but always out performing them with a more practical answer to the violence they are threatening. Of course there is more to understand but bottom there IS A WAY for you not only to survive over 50 but THRIVE under these circumstances.
