I would disagree with nightwork4.
There is indeed... it all starts at home. Parents should inculcate into the child's mind/brain nothing but good. I'm a living example of it.
I have friends who are drug addict and even obsess with sex. But because my parents raised me well and never try to put something bad in my mind while I was young, I am able to resist anything that I think is bad for me.
...and I will do the same with my daughter.
