Nature Genetics talks about research done on the genetic influence for depression, neuroticism, and happiness. We all know the connection of these feelings and mental states with our brain, but this study shows that we may be genetically pre-disposed for them as well. Unfortunately, with everything related to genetics, nothing is clear cut and simple. What we experience and how our genes present themselves are going to be a combination of millions of factors. In the article they talk about how a lot of people find it useless to keep investigating these types of discoveries because of how many "if-then" scenarios there could be. They relate it to Huntington's Disease and how even though we know how it works, we are still no closer to knowing how to treat this devastating disease. So even though they may have been able to identify where we have a genetic pre-disposition, that small fragment may have not been the cause of depression, neuroticism, or happiness. Basically....what's the point?
I believe the important part here that some people may miss is that yes we may not be able to control anything(outside and biological factors), but we are understanding little by little what makes us, us. To be able to understand something so complex is a miracle on its own. Hundreds of years ago, they blamed depression on a curse or witchcraft. Today we have a better understanding of these things and can raise awareness to help instead of attack people with metal health issues. Everyday we learn more and can share this knowledge with others.
