If you worry too much about others you have more opportunities to have psychological problems

There are many simple ways of becoming more pleasant to the people around you, and we want to believe that all goodness and consideration will be appreciated.

However, a new study shows that being kind cannot only bring us good. According to Nature Human Behavior, people who are defined as sensitive to injustice or inequality are more likely to show symptoms of depression than people who tend to be selfish. For the experiment, lead author Masahiko Haruno and a team of researchers have seen whether the thought model considered “pro-Social” (meaning self - sacrificing) is linked to long-term clinical symptoms of depression. They started by giving almost 350 people a personality test to determine if they were in “pro-Social” or “individualist” (egoist). Then they measured people's desire to share financial resources with less fortunate ones. By examining the brain of pro-Socials and individualists using functional magnetic resonance images, they were able to see which areas of the brain have been activated during specific situations. Brain images were quite different between two types of people. In situations in which money was distributed in an uneven way, pro-Social people showed stress while selfish people showed stress at the moment that only other people took more money than they did.

According to researchers, better people are more susceptible to depression because they are more likely to experience extreme sensitivity, guilt, and stress. And this emotional sensitivity is linked to the deepest and most automatic regions of brain countries that are easy cause for depression.
