So...let's talk about going to Mars forever

I admit, I had a great time writing this story on the Mars One program, despite the fact that it's something of a wild, potentially unfeasible idea. I think that's because the possibility of something like this actually working is enough to get your imagination rolling...which leads me to ask...if you were selected to train for seven years and then embark to colonize Mars, and never come back to Earth, would you do it? And why or why not?

Personally, I'd probably take a pass. I think. But I haven't really decided yet....oh, the pro and con list is endless.
