Brain Damage: Do Football Helmets Help?
September 5, 2016
Recently, the National Football League is facing a 765-million-dollar lawsuit filed on behalf of more than 4,500 former players regarding the concussions and potential chronic traumatic encephalopathy (CTE) sustained during their careers. Similar lawsuits are underway against the National Collegiate Athletic Association as well as the National Hockey League, and football helmet maker Riddell is facing multiple lawsuits over claims about the effectiveness of their helmets at protecting athletes from concussions.
Foam or Knuckles—Navigating the Illusion of Safety
January 18, 2016
If you really want to understand how gloves contribute to the safety of our athletes, especially when it comes to their brains, take a closer look at the physics behind taking a punch with a bare fist or a glove.
Physical Reaction to Information
December 14, 2015
Our right to physically defend ourselves is widely accepted in the contemporary world. Most countries have laws protecting the individual from prosecution when he or she is under direct threat and must defend against bodily harm or even death. What is less clear, though, is the degree to which we are allowed to protect ourselves in that narrow window when an aggressor has decided to attack but has not yet attacked.
Nonphysical Reaction to Information
November 2, 2015
We all have the ability to use our instincts. The problem is that we often bury that inherent skill under a lot of what we need to learn to get along in contemporary society. So sometimes we may get a warning message about a potential threat, but then we choose to ignore it, perhaps out of doubt in ourselves, and our feelings, or perhaps because we just don't want to believe we may be in danger. The first task, then, is to hone our instincts through improving our ability to experience anxiety and to proficiently process the information coming in from our environment.
Motivation of the Warrior
October 12, 2015
The motivation of the individual or group plays an integral role in determining the final outcome when facing a combative or self-defense situation. Intention that is positively grounded increases focus, strength, speed, and endurance. Think of a mother lion defending her cubs. She experiences anxiety but is fearless in protecting them. People are the same. Through my years of experience, I am convinced that when we are motivated by what is good, we will eventually prevail over those who are not. We all choose to live by either service, which we might even call love, or power.
Power Issues Relating to Women - September 28, 2015
According to the World Health Organization, one in three women worldwide will be the victim of violence, including sexual violence. Over twenty-two million women in the United States have been sexually assaulted. The FBI estimates only 46 percent of these assaults are reported. These statistics tell us it is vital for every woman and girl to take courses in combatives, both armed and unarmed. This may seem drastic, but facts are facts, and the danger is real.
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.
Psychology at Work: Developing the "Third Ear" and the Mob Boss - August 31, 2015
In his book Listening with the Third Ear, the psychologist Theodor Reik applies the third ear principle to the process of practicing psychotherapy. He says the proficient psychotherapist must be attuned to the instincts, the third ear, in order to truly understand clients and be sensitive to their needs. In exercising this faculty, we hear what is being said, but another "listening" is taking place as all of the information is coming in through the senses, prompting unconscious responses in the form of associations and spontaneous thoughts and feelings on the part of the therapist.
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.

The Dojang—A Safe Haven During 9-11 - September 6, 2010
On September 11, 2001, I was employed in New York City at a job that I would soon vacate in favor of teaching martial arts professionally. On that tragic but stunningly brilliant morning, I stood on the corner of Fifth Avenue and Nineteenth Street watching the destruction of the World Trade Center unfold before my very eyes.
Listen to the Subtle (and Not-so-Subtle) Warnings - January 6, 2010
We’ve spent much time writing about awareness on the street. It’s important in relationships too. Don’t turn your brain off when you walk into your home.
Violence: What Everyone Needs to Know About Fighting - August 2, 2009
According to the Bureau of Justice Statistics, men commit about 80 percent of all violent crimes in the United States, serious stuff like homicides, rapes, robberies, and assaults. Men are twice as likely as women to become victims of those same violent crimes, except for rape.
Mob Violence Is An Eruption With No Warning - February 17, 2009
Gang violence gets a fair amount of copy in the media. But another form of violence is mob violence.  Mob violence rises up, explodes, and then recedes.
