Playing with Genes

New research has demonstrated that genes can change. For example, identical twins with the same genes can turn out different. The impact of the environment has an influence on how that person is going to be.  The things what makes you who you are not only nature and nurture but also biological mechanism. The biological mechanism can switch genes on and off. These switches can affect the person in every way. Tim Spector who is head of the department of twin research in London questioned the influence of genes. Studies have shown that they can change a person’s life by influencing its genes.

If this is really true and people can really change a human’s life by influencing the genes it would be amazing. I am just imagining how life will be when there is for instance no obesity anymore or other genetic inheritance. The only thing I don't understand is why they choose for drastic things. In the article it also says that there are other natural ways to control for instance obesity namely,  exercising. Research has shown that when people exercise they switch the FTO gene off which is key for causing obesity. I think people should try to lose weight first by another way than playing with genes.
