DNA testing is now so advanced and accessible that there are different forms of screening to answer different questions. It is not enough to use genetic testing to learn more about where we come from.
In addition to this, we also want to find out more about who we are as individuals. There are tests about the deepest genetic signatures of our personality and preferences.
One of the more interesting testing options is to test for key markers for getting in better shape. The theory here is that a better understanding of our genetic makeup can highlight reasons why certain approaches to diet and weight loss work.
