One opinion that I have had since I was in high school is this:
I don’t care what martial art you study, what color belt you have, or how skilled you are, physical defense has limits. A 6 year old with a black belt in karate can’t beat up a full grown adult. A 100 pound woman isn’t going to beat up a 250 pound man, unless that man is in poor physical condition.
That opinion wasn’t a popular one, but it’s true. Skill can only do so much, but at the end of the day, physical strength, stamina, and size are just as important. Let me show you:
That doesn’t mean that skill is to be ignored. It means that what skills you do have should be viewed through a realistic lens. A 100 pound woman still is far outclassed in strength. That 100 pound woman believing that taking some krav maga classes is going to enable her to take on and disarm a full sized man is going to give her the overconfidence to go places and get into situations that she is not equipped to handle.
She let her classes where she practices set moves against compliant adversaries give her the false confidence that she can take on grown men armed with weapons and prevail, when in reality, she can’t even take on a man when given a distinct advantage, and in this case, the man was holding back and trying not to hurt her.
The same is true of people who carry guns. Many people only carry in “bad neighborhoods” and allow that firearm to pull them into places where they wouldn’t go if they weren’t armed.
Have a realistic idea of what training and weapons do for you, what your capabilities are, and know how and where you should be. One thing that I have learned by taking BJJ is that I have flexibility as my advantage, but I don’t have the stamina and cardio of a 23 year old any longer. In many cases, a 22 year old will be stronger and will be in condition to outlast me in a protracted fight. In any hand to hand, I must endeavor to win the fight early, because I will lose a protracted battle.
Be realistic in your own assessment of your abilities.
