S.M., sometimes referred to as SM-046, is an American woman with a peculiar type of brain damage that physiologically reduces her ability to feel fear. First described by scientists in 1994, she has had exclusive and complete bilateral amygdala destruction since late childhood as a consequence of Urbach–Wiethe disease.Many of their studies begin with the amygdala, an almond-shaped structure that is considered the hub for fear processing in the brain. While the amygdala was once thought to be devoted exclusively to processing fear, researchers are now broadening their understanding of its role.The amygdala participates in the regulation of autonomic and endocrine functions, decision-making and adaptations of instinctive and motivational behaviors to changes in the environment through implicit associative learning, changes in short- and long-term synaptic plasticity, and activation of the fight-or-flight …
Is it possible to not have fear : SM has an unusual genetic disorder called Urbach-Wiethe disease. In late childhood, this disease destroyed both sides of her amygdala, which is composed of two structures the shape and size of almonds, one on each side of the brain. Because of this brain damage, the woman knows no fear, the researchers found.
How rare is it to have no fear
Fear is one of the most basic emotions that we have, so it's next to impossible to find someone without it. DAMASIO: Fear, it's a very towering emotion. SPIEGEL: In fact scientists have identified only about 400 people on earth with the condition that was causing fearlessness in SM.
Why is fear so powerful : It's a response the brain has learned in an attempt to protect the person. It's as if the brain's alert system triggers a false alarm, generating intense fear that is out of proportion to the situation. Because the fear signal is so intense, the person is convinced the danger is greater than it actually is.
Fear Is Physical
Stress hormones like cortisol and adrenaline are released. Your blood pressure and heart rate increase. You start breathing faster. Even your blood flow changes — blood actually flows away from your heart and into your limbs, making it easier for you to start throwing punches, or run for your life. Practicing stress-reduction techniques such as meditation, deep breathing, and exercising. Work through symptoms of PTSD, severe anxiety, or panic with a trained professional. Eat a healthy diet, drink water throughout the day, and get enough sleep to contribute to general good health.
Where is fear stored in the body
Our stomachs and intestines store our feelings of fear. The adage, 'I am sick to my stomach' justifies this. Fear is another negative emotion that has far-reaching repercussions on our health. It can cause digestion problems, pain in the gut, bloating, constipation and even Irritable Bowel Syndrome.SPIEGEL: Now, fearlessness like this, that is a biological inability to feel fear, is incredibly rare. Fear is one of the most basic emotions that we have, so it's next to impossible to find someone without it.Short answer, no they do not exist. Living life with the mindset of wanting to conquer fear is healthy but, living life pretending that one is not afraid of anything can be misleading and damaging. What Are the Rarest Phobias

Who is stronger than fear : Love is stronger than fear, but fear will win out unless we allow love to empower sacrificial action in the world. Love is stronger than fear, but only if we participate in love. Only as we entrust ourselves to love. Only as we allow love to nourish us.
Is fear learned or natural : Fear can be innate or learned. Examples of innate fear include fears that are triggered by predators, pain, heights, rapidly approaching objects, and ancestral threats such as snakes and spiders.
Is fear just a feeling
Fear is an emotion that has played a significant role in our evolution and survival. It can be crushingly strong and paralyzing, but it's also necessary for our safety. Damage to the amygdala can often be caused by stroke, traumatic brain injury, and other neurological conditions. Individuals with amygdala damage may experience various emotional and behavioral effects such as impaired decision-making, hypervigilance, or anxiety, just to name a few.The team demonstrated that when the amygdala was turned off, patterns of brain activity in other brain regions either decreased or increased. Areas known to be well-connected to the amygdala were particularly affected, but so were brain regions that have no known connections to the amygdala.
Is fear good or bad : Fear can be healthy. It is programmed into your nervous system, and gives you the survival instincts you need to keep yourself safe from danger. Fear is unhealthy when it makes you more cautious than you really need to be to stay safe, and when it prevents you from doing things you would otherwise enjoy.
