Yaw-Yan in my younger (and lighter) days, It was most effective.
Also, something that most (maybe all) of you I am sure have never heard of.
It was called Omnite. As it was mostly a mental dicipline,(extreme muscle control)
I have never seen any books written on it. I have not even seen it mentioned in 25 years?
It was some crazy stuff but downright lethal if done properly. I saw something similar
in a move called "The One".. Don't know the actors name who portrayed the bad guy in the
movie but it was apparent that he was at least familiar with Omnite.
Too old and fat for those kinds of things now, But I had my day
I am sure that if I went to kick any thing much higher than someones butt, I would do serious
damage to the seat of my pants.
