Scientists from the London School of Economics and Political Science, United Kingdom have successfully identified a gene trigger a sense of happiness which is called the 5-HTT. Genes are happy to help nerve cells to recycle the compound serotonin, known to relate to mood and depression.The study mentions 5-HTT is present in the form of 'old' and 'short'. Individuals who have two kinds of variants of the 'old', one from each parent, tend to have many more happy gene content of the other combinations. The smaller the feeling of happiness is for people born with two types of short genes .
"It has long been suspected that the 5-HTT plays an important role in human mental health, but this is the first study that could explain this gene," said Jan-Emmanuel De Neve from London School of Economics and Political Science, who led the study.
"Our results reveal the relationship between happiness and the 5-HTT gene," he added. The results are reported in the Journal of Human Genetics. For this study, scientists analyzed the genetic data of about 2,500 people. "Finding this gene helps us to explain why some people tend to be happier than others," said Jan-Emmanuel.
I was so amazed upon reading your article. Very informative and really interesting.
