Fear

Fear triggers immediate changes in you just as in other animals - your hair stands on end, your heart beats faster, and your body gets ready to either attack or run. When you recognise danger, or feel afraid, you are using an area of your brain called the amygdala. People with damage to this area can no longer recognise fear in others.

Feeling afraid helps you to react to dangerous situations.
