Biodome

Because this blog is "Culture and Mars" I would like to post the question to anyone who wants to respond as to what the culture of living in a biodome would be like. As stated before it can support 12 people for 3 years. What would it be like to live in a dome with the same 12 people? Do you think the social implications of this would be too hard for people to deal with? What do you think about all of this?
