Silly Game Time: Would you rather spend one year in a zero gravity environment (like a space station) or one month in a completely underground bunker?
Adequate food, water, entertainment, and company from other people are supplied in both. Physical safety from the environment are guaranteed in both (though I guess you could be really clumsy or start a fight if you wanted? point is, there will be no meteorites or earthquakes).
I would prefer the space station and, in the hope that it doesn't cause any problems, go absolutely crazy in zero gravity. In the style of old cartoons. A bit like Tom and Jerry.
