It is how some of us are more prone to being pre attentive of external threats than others. When ppl r on a lookout fr wht could go wrong they tend to evaluate even the most neutral situation as negative n dangerous n then activate an anxious response.

There are lot of factors responsible for our personality and behavioural traits. Our personality and behaviour are bi --product of our genetic composition inherited from our parents, our environment, our neighbourhood and so many other factors. From all these circles we learn to live, learn to perceive things and learn to manage the situations. So every body experiences a different environment and tend to develop different strengths and weaknesses to cope up with life's paradigms. Thats's why we are different.
