Defense

Like a country, we have defense system for our body.
There are two kinds of biological defense system, internal and external
Our external biological (EB) system is what we call psychological defense system

Our IB defense system is an emotional system of chemical process or what we call immune system
It is automatic and without our awareness
however, we can be aware of some internal violation through our emotional experience, feeling that trigger us to action to provide external intervention (medication or surgery)
The villain for IB defense is any chemical and biological entity that cut, eat away, or kill our cell and body or mutation or degeneration of cells in our body.
The external intervention (prevention or recovery) service is usually done by medical service.

Our EB defense system is what we call psychological defense system.
It is a sense/perception (mental) that trigger emotional system that motivate action to provide internal (mental intervention) and external (using people, thing, and environment) intervention.
Our EB defense system is defense system against external behavior and promise of behavior.
A dog growl, a snake hiss gives warning to stay away. A human threat gives promise to attack.
Animals don't attack, they are protecting their safety or meeting their basic needs.
Human being attack to attack, human overattack even when they feel safe and their basic needs met.
because human has mind that can overperceive or imagine to prepare future safety and future basic needs.
This is why our mind move all the time, to anticipate.

This defense system is one of the basic human skills: to meet physical needs and social skills.
We have our EB defense system against any abuse or bully or violation both in action or words
There are those who attack by witholding, or refusing social cooperation or communication, like a private demonstration
There are those who attack by witholding physical nneds.
And there are those  who simply attack threatening our safety, either by action or promise to action.
Our emotional system is part of our biological system is always working automatically
However, psychological warfare favors those who can still their  feeling (psychological emotion) and mind.
feeling/sensation (psychological emotion) is emotional reaction to imagination of mind (perception and imagination), not to sense information (impression)

so the process is like follow: mind (environment) - feeling - mind (digital senses) - mind (imagined behavior) - feeling - mind (environment) - behavior

Animal: Environment (external senses) - emotion (internal senses) - behavior - environment (external senses)

Human: Environment (external senses) - mind (perception + imagination) - feeling (internal psychological senses) - mind (digital senses) - mind (imagined behavior) - Feeling (new internal senses) - Mind (new digital senses) - mind (new environment) - behavior.

let the body move, let the emotion pass u by, just don't believe them
