Go to the following website, 

http://www.dimensionsmagazine.com/dimtext/kjn/people/heaviest.htm and read through the long list of people who have made it into The 900 Club, which is a club for people who have reached 900 pounds in weight. After reading through all the different situations, write a short paper on the situations of obesity and how these people became obese. Do any of them have similar situations or causes for their obesity? What are some possible underlying causes for obesity?
