Jacque Fresco of the Venus Project talks about humans being a victim of their culture
Examples of this would be a child brought up in a very religious family, who because of their upbringing believes firmly that God (or a God) created the world and everything and everyone in it. Than you can have another child who had parents that where strong atheist's, who because of their upbringing believes firmly that the idea of a God that created everything is just ridiculous!
The idea of being a victim of culture is very true even when it comes to strength and conditioning. Think about. If I was brought with a powerlifting background I would more than likely train my athletes like powerlifters. If my first introduction in the field was to a certain guru, I would train my athletes and clientele very similar to how that certain guru does.
The fact of the matter is, is that you cannot be mad at anyone for the way they are, how the act, how they think, and how the train people, because we are all victims of culture to a certain extent, some more than others. Nobody is born into the world with any prejudice. This is all learned from environment/ culture.
So this is why it is essential we develop open minds, all of us. Let us consider all opinions and ideas when it comes to life and training systems ;-)
