The University of Michigan is conducting a research study in which they are compiling DNA data to learn more about how our genes affect our lives and how they may contribute to various diseases. They use a Facebook app to conduct health surveys. Once you have completed enough of them they send you a spit kit for collecting your DNA. You will receive your DNA data as a computer file. Participation in this study is free. I just received my spit kit and filmed this video to show it to you.
