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.

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.

Never Hit A Girl…Unless She's Armed
September 29, 2014
Sun Tzu and Miyamoto Musashi made no distinctions regarding gender. To them all adversaries were defined as combatants. In today's world, distinctions of gender are made by friends, family, police, and the courts. The role of combatant is, oftentimes, secondary. While experienced bouncers, bodyguards, law enforcement officers, soldiers, jail guards, and martial artists know that women can be just as dangerous, or possibly even more so than men, (such as instinctively going for the eyes during an attack) the courts don't often see it that way.
Sport versus Combat - May 27, 2013
It was the first time I’d ever made it to the finals. Win and I’d take home the first place trophy; lose and it’d still be a pretty cool piece of hardware. I’d come in third a couple of times, but the little statues weren’t nearly as prestigious as the big ones. And I really, really wanted to earn one of the big ones.
The Ground. The Dirty, Filthy, Dangerous Ground - April 29, 2013
The Raiders fan had biceps that could put Hulk Hogan to shame and a physique that was nothing short of awesome. He stood out in a bar full of average guys, not only because he was ripped, but also because he was the only person cheering for the other team, the only one doing it vociferously anyway.

Use Neck Cranks or Chokes to Fight an Adversary - January 9, 2012
In single combat, we can confuse the enemy by attacking with varied techniques when the chance arises. Feint a thrust or cut, or make the enemy think you are going to close with him, and when he is confused you can easily win.
Shu-ha-ri - The Phases of Mastery in a Dojo and with a Pen - September 19, 2011
It’s not unusual for martial artists to talk solemnly about “the Way” and how the life lessons that have been created through training spill over into the rest of our lives.
Channeling Sekishusai - July 18, 2011
One of the most important aspects of martial arts training (and the thing that first attracted me to the activity) is the linkage between things of the body and things of the spirit. There’s a lot to be said for the physical aspects of training—and if most people are anything like me, it’s almost addictive.
Sanchin, Shime, and Hard Impact - July 4, 2011

Positive Attitude Required for Black Belt - May 30, 2011

The goal is to achieve a better understanding of sanchin kata through the mechanics, history, and applications of the kata.

Mob Violence Is An Eruption With No Warning - February 17, 2009
