Is what will happen in our lives determined more by our genetics or by how we choose to live? While this question has been debated for over 100 years, recent advances in DNA technology have pushed the debate into new territory, stoking both interest and fears in the general population. Zar discusses how genetics influences our traits and our risk of disease as well as how genetic testing can give us insight into our personal disease risk. He will also discuss how aging and diet can affect our genetic makeup and what genetic studies suggest about how we should live our lives.
