Guns, Knives, and the Hollywood Death Sentence
September 21, 2015
In order to become a successful screenwriter in Hollywood, you need to watch a lot of movies, so you can learn from the screenwriters who came before you, and so you can get a feel for what else is out there and popular today.  Unfortunately, this important part of a screenwriter's education is also how Hollywood ends up propagating and recycling incredibly stupid ideas over and over again to the point where the audience just accepts it without question.
Protecting the Brain from Trauma: A Home Experiment to Show We Can Do Better
September 7, 2015
If you put on a football helmet right now and smacked yourself in the head with your hands, you might notice you can hit yourself pretty hard before you start to feel pain.

About Junbi Undo—Part 2 - August 22, 2010
"Lift things properly, hit things with care", this maxim should be at the forefront of your mind when embarking upon the study of traditional Okinawan hojo undo.

About Junbi Undo—Part 1 - August 16, 2010
In an Okinawan karate dojo, warming-up exercises are known as junbi undo, preparation exercises. Within many Western schools of karate today, the warm-up exercises often have little in common with the mental activity that follows, neither do they always relate particularly well to the physical demands placed upon the specific muscle groups and tendons throughout the body that are about to be used in the karate training itself.
Thwarting Terrorist Bombing Through Awareness—Part 2 - June 28, 2010
Awareness of timing has to do with the time of day during which terrorist attacks are most likely to occur. Terrorists are very conscious of media attention, timing attacks carefully to achieve the highest possible level of public impact.
Thwarting Terrorist Bombing Through Awareness—Part 1 - June 21, 2010
This article was written right after the bombing on the London transit system in 2005 and was published in Neth Publications. It is just as timely today with the recent bomb threat in New York City in April 2010. Although some of the statistics are five years old, the core of the article tells you that awareness is the key to survival...
Wicked Words that May Kill You - March 15, 2010
While sticks and stones can break your bones, your words may actually kill you. They can also save your life. Having to be right despite the cost, reacting indignantly in the face of a threat, or insulting an adversary often guarantees that a conflict will escalate to violence.
It’s Hard to Fight When You Can’t See - February 1, 2010
I purchased the wrong type of coffee yesterday, a ground drip blend rather than the whole bean variety that I normally buy. When I popped the top of the vacuum-sealed can, a blast of grit exploded into my face and left eye.
¿Golpeas al objetivo? - December 14, 2009
Nunca dudé, al ponerme frente a Kanazawa sensei, que iba a "enchufarme". Pero tenía la absoluta certeza de que no iba a hacerme daño.
Are you hitting the target in Karate? - November 30, 2009
There was never a doubt in my head when I lined up to face Kanazawa sensei, I knew he was going to 'plug' me.
Remembering Chojun Miyagi - November 11, 2009
Among the huge number of so-called karate styles in the world these days, all can be traced back to the island of Okinawa, the largest island in the Ryukyu archipelago that stretches from the southern coast of Japan to the northern tip of Taiwan.
Hojo Undo: Traditional Karate’s Forgotten Training Methods - September 9, 2009

Big Rocks: The Hidden Values of Traditional Karate - August 13, 2009
A philosopher and teacher of the ‘Way’ began addressing his students. He produced, from behind a screen, a large glass container and a box of fist-sized rocks.

Never Surrender - June 16, 2009
The goal of self defense is not to win a fight, but rather to avoid combat in the first place. After all the only battle you are guaranteed to walk away from unscathed is the one you never engage in. Taking a beat-down can seriously mess up your life, yet winners have consequences too.
Spotting an Adversary’s Tell - April 27, 2009
In more than twenty years of working stadium security I have witnessed, interceded in, stopped, or prevented well over 300 fights. Yet in all that time I have only been sucker-punched once. I didn’t like it much, but obviously I’ve managed to avoid repeating that mistake by taking it upon myself to pay close attention and learn from the behavior that precedes violence.
