2. Unnatural Causes
1. Describe the body’s stress (fight or flight) response. How is chronic stress different? How might chronic stress increase the risk of illness and disease? 2. How do the lives of Jim Taylor, Tondra Young, Corey Anderson and Mary Turner exemplify concepts like the wealth-health gradient and the importance of power and control? What does comparing data maps of disease rates in the different Louisville council districts reveal? What might explain observed differences?
