In your blog post discuss the concept of using identical twins in an experiment with one being the test subject and the other the control. Discuss how this will work, what it could show the experimenters, and the advantage of using identical twins
The concept of using identical twins in an experiment where one is the test subject and the other is the control is very interesting. In the article that was read Scott Kelly (an astronaut) has a twin brother that is a former astronaut himself. By using the twin brother on Earth as a control subject it shows how different a person's health will be after being in space for so long. In this scenario Scott is the test subject and his brother, Mark, is the control subject as he is not being affected by zero-gravity space. An experiment like this would work by keeping two people on the same diet, exercise schedules, and various other factors that could affect one's health. One person would be sent into space and the other would be kept on Earth. The two subjects would show the experimenters how exactly a person's health is affected by going into space for a certain period of time. The advantage of using identical twins is because they are essentially the same person through variables like age, sex, history, and anatomy which could block out a few lurking variables that affect each subject's health.
