New Delhi, Scientists have found that some people are born optimists because they have inherited a happy gene. The finding may help to explain why some people are always miserable while others tend to look on the bright side, the Daily Mail reported. Professor Elaine Fox at Essex University showed more than 100 people positive and negative pictures on a computer screen, such as growling dogs and smiling children. Volunteers supplied a sample of their DNA and they were tested to see which version they carried of the 5-HTTLPR gene, which affects levels of the feel-good chemical serotonin.We inherit either two short versions, a long and a short version or two long versions of the gene.Those with two short versions of the gene managed to focus on the positive images and avoid getting upset by the negative ones, according to the research.
