Yeah, I think I'd watch this. I tend to avoid reality TV like the plague, but this sounds really interesting.
Well, most "reality TV" is geared more towards tossing a bunch of whiny drama-queens in a room together and watching them bounce off of each other as they play out their own self-important lives as they vie for their fifteen seconds of television fame.
On the other hand, most of Discovery Channel's forays into the genre are really good because they actually focus on REAL people living their REAL lives: Deadliest Catch, Pitchmen, and so on. Even though this show isn't about these people's real life, it seems like it's going to focus on showing the science of survival in this situation and how it effects those who find themselves in it. I expect it to be much more like DC's own The Alaska Experiment than Survivor.
