Learning self defense techniques was an integral part of every boyhood life before being initiated into manhood till not very long ago in some Asian, African, and Western communities and tribes. But with the sudden speeding of civilization into our lives, these ancient self defense art forms are practiced by limited numbers and it has evolved and taken many forms. While some schools emphasize learning such skills even from a young age when they are most vulnerable, so that they lose fear and develop enough confidence to face the world with physical as well as mental confidence. Though our purposes and scenarios are entirely different, the ancient tutoring on the fine martial arts of self defense might have been mostly due to necessity to ward of enemy invasions and to guard territories. Though some of us might have been able to learn at least a few self defense tricks from our martial arts teacher, some might not even have thought about it. Yet it is not necessary that you need to be a martial arts expert to guard your self against an attack or an act of violence. There are simple and compact solutions that can safe guard you in any kind of vulnerable or threatening situation.
Living in cities is a risky business. Accidents happen every day on the streets we cross. Somebody who drove a few cars ahead of you might be sitting lifeless over the steering wheel after a crash and we pass by thinking about the temporal nature of life. We might even know somebody who might have been stabbed or mugged for money. Not a day passes without report of crime in the papers or on TV. There are muggings, rapes, and violent crimes of passion that take a daily toll of the lives around us. We who watch the news and empathize with the victims never might imagine something similar could happen to us too if we were exposed to the same certain situations. Yet it is only a few of us who might start thinking about buying something or the other to defend your self with in case of an attack and very few who would go all the way.
But that situation is changing fast. A recent world wide survey of densely populated cities indicated a surge in crime rate with the rise in unemployment prompted by the economic recession. Also reported is the increase in sale of self defense equipment of which stun guns were the most sought after mostly due to the ease of its use, the compactness and the affordability. What more could you ask for than stun guns when it comes to personal protection? The design element of the stun gun also is an important factor for stun guns being considered the most popular choice of self defense equipment. Stun guns are easily concealable in your clutch bag. Stun guns are available in the shape of cell phones, key chains, flashlight light, penlight, lip stick or even as an iPod stun gun. The electroshock discharged from the stun gun at the press of a button has the capacity to put even someone the size of a WWF superstar to rest for a few minutes giving you enough time to escape. With a stun gun in hand you would never be playing the victim.
