Fear And Phobias

What is your greatest fear? Do you know the answer? A lot of people don't. We just know that we sometimes feel fear and most people don't like it. Sometimes, people like the feeling of fear.

It automatically sends a signal to the prefrontal cortex , which causes the prefrontal cortex to invoke the fight-or-flight response. This happens when the phobic gets near, sees, or, in severe cases, thinks about the thing they are phobic towards.
