Ever felt you can't enjoy being happy in case you tempt fate? If so, you're not alone.
Millions of people actively avoid feeling happy because they think it will cause something disastrous to happen to them, research has revealed.
New Zealand psychologists have found that we shy away from enjoying the moment because we fear it leads to unhappiness and other unfortunate consequences.
Others - both in Western and Eastern cultures - avoid happiness because they are convinced it makes them a worse person and others may see them as selfish, boring or shallow.
People in non-Western cultures, such as Iran and neighbouring countries, worry that their peers, an 'evil eye' or some other supernatural deity may resent their happiness and they will eventually suffer any number of severe consequences, the study found.
In America, however, it is almost taken for granted happiness is one of the most important values guiding people's lives. Western cultures are more driven by an urge to maximize happiness and minimise sadness.
