Four Russians, a French guy and a German guy just kept each other company (on Earth) for 105 days. The idea is to see if people can get along for a length of time comparable to a Mars Mission. My question is how do you think they are going to get on with each other if they have to sneak a wank in close quarters? That's a whole lot of spunk. In zero G is it going to get stuck everywhere? Can it be recycled? How will they keep the peace if these guys can't wank for six months?
