In my late 30's I witnessed a frail looking old man with a wispy blue beard he had dyed dressed in a long orange rope surrounded by 5 young and robust line backers ready to tackle him. As they rush to tackle him, he vanishes and the attackers collapse into a heap revealing that the old man is actually a Pakua Zhang Master. The old man smiles, not all martial arts are created equal, Pakua Zhang and Aikido, both a circular art form is able to defeat multiple attackers. NOT ALL operating systems are created equal.
