Fear

What is Fear?
Emotions play an important part in our daily lives. Fear is one such emotion that is pre-programmed into all animals and people as an instinctual response to potential danger.
As for what is fear biologically speaking, when a person experiences fear, certain areas in their brain such as the amygdala and the hypothalamus are immediately activated and appear to control the first physical response to fear. Chemicals such as adrenaline and the stress hormone cortisol are released into the blood stream causing certain physical reactions such as:
Rapid heart rate
Increased blood pressure
Tightening of muscles
Sharpened or redirected senses
Dilation of the pupils (to let in more light)
Increased sweating


..............so dnt fear?????????
