In what may perhaps become a series of science diaries, something DoDo asked me I think months ago and specifically on climate change, the first bit is brief and is about genetics and happiness... This piece heavily relied on the science column of the Dutch newspaper NRC Handelsblad of past Tuesday, hence translation errors are entirely mine.
Although I'm not much of an expert in Medicines, I'm willing to bet I'm an expert in happiness - as are we all, as long as it is our own, personal happiness. And the focus here should be on that word: personal. Happiness is in general all about your own happiness, your own state of mind which directs (or sometimes dictates?) how we respond to the outside world. Some people need a little help from other people (e.g. psychiatrists) to find out how their happiness is exclusively personal to them, but no one can really tell you how to be happy in the best way. Except yourself.
And now there is new research which indicates that happiness is not only personal, it's also hardwired within our body. It's our own genetic code that also plays an important role, and a larger part than was previously estimated.
From the diaries - emphasis added ~ whataboutbob
Happiness is chemistry within the body. Chemistry in the body is described by the genes in our body, which are packed into our DNA. Yet it was speculative at best to consider that a psychological state of mind could be coupled to our genetic code. Preliminary results of dr. Meike Bartels at the Biological Psychology, Free University, Amsterdam, however indicate there is a real link between the two.
As often is the case when the debate revolves around nature vs. nurture, identical twins were used to determine to what degree DNA plays part in experiencing happiness. The outline of the approach works like this: principally, twins are not differently happy than normal people and identical twins are genetically the same. So, if there are differences in experiencing happiness between the identical twins, the surrounding environment must be a factor.
However, for non-identical twins (which do not have identical DNA, but share half of their parents) a different experience in happiness could be caused by either their genes (nature) or their environment (nurture). Now, if identical twins show far greater similarities between experiencing happiness than non-identical twins, this gives an indication for a genetic link between feeling happy. And this is what dr. Bartels and her team, studying over seven hundred twins in the age range of 14-16, have found. The statistical model predicts that the role of our DNA in feeling happiness is about 50 percent - far greater than was believed possible.
Bartels: "Happiness is not connected specifically to social status or stature in the society. Taken by the mean values, intellectual people are no happier than non-intellectual people and rich people are no happier than poor (in the Netherlands). There is no clue as to what biological factors contribute to feeling happy, never mind the involvement of genes."
Bartels further cautions that her findings are only preliminary and wants to expand them to a larger group of adolescents, up to 4500 twins. She also is busy with setting up several methods to gauge happiness - one of the contested points in her research. Specifically she wants to measure a person's perceptions of quality of life, satisfaction with life and personal happiness.
Bottom-line, however: grouching people, beware. If more proof of the happy genes lies ahead, you can forget about blaming others. It has always been about you.
