No thanks I would not want to go on a one way mission to Mars, my worrys include
1. The large cosmic ray radiation dose, I know in the manned moon missions then plan was to turn the space ship around to give the humans as much shielding as possible from the sun if it went into a nasty state, they could then get the humans back to earth within 6 days to reduce the exposure time. With the mars mission no easy abort option exists, you could end up with a nasty proton / heavy ion dose. Maybe if you are unlucky you could get a dose which would cause nasty acute effects such as bone marrow damage, I know that the medical management of a radiation overexposure case is complex and not the sort of thing which could be done in a space ship. For a person with moderate bone marrow damage you would needs loads of blood transfusions, antibiotics and exotic drugs.
Given the choice I would rather get a moderate exposure on earth doing something worthwhile, at least after a moderate dose I could go home and put my feet up in my own home. Also if I was at a place like Fukushima during the worst phase of the accident tooled up with the right tools I would be able to decide at what point I had reached the maximum dose which I was willing to get before packing up and going home.
2. I would never be able to visit any of the places I love on earth again
3. I would never be able to go for a walk in the park again
4. I would have to leave my wife and family behind
5. I would not be able to pursue my special interests while in space, if I went to the south pole on a scientific mission I would have to leave some of my special interests behind but I could take others, plus it would only be for a limited time.
6. I think I woud hate the bland diet of tinned food
