Most people relate stress to physical symptoms like an upset stomach or headaches. Research has suggested that negative emotions and thoughts may also have close links to our brain. Researchers have started finding out why we tend to remember negative things more strongly and, in more detail, than good ones. “The hrain handles positive and negative information in different parts. Negative emotions involve more thinking, and the information is processed more thoroughly. Thus, we tend to ruminate more about unpleasant events and use stronger words to describe them than happy ones," said Clifford Nass, a professor at Stanford University.

Rick Hanson also shares the idea that our minds naturally focus on the bad and discard the good. He stated, "negative stimuli produce more neural activity than do equally intense positive ones. They are also perceived more easily and quickly." This was obtained from his little experiment in which twenty people were asked to look at pictures showing anger or happiness. The participants could identify angry faces faster than happy ones even if it was so quickly.

In a journal article Baumeister co-authored in 2001, "Bad is Stronger Than Good", he concluded, "bad emotions, bad parents and bad feedback have more impact than good ones." This is "a basic and wide-ranging principle of psychology". Thus, Baumeister and his colleagues noted that bad incidents, such as losing your dreamy job and breaking up with your girlfriend or boyfriend, may have a greater impact than landing a job or receiving a marriage proposal.
