Such lives don't have enough dopamine hits to keep people of such dispositions around long. Training for ultra-marathons (and running them) is painful and tedious. The thing that people need are goals. For example "survive on Mars for 2 months". Then the next person will come along and say "I bet I can do in for 3". Then 6, then 12. And if enough people do it, suddenly you have a "base camp" from which to run your extreme survival competitions. The dopamine drip will last a long time. Eventually, someone will fall in love with Mars in the same way they fall in love with Everest or El Capitan, or whatever, and then a colony can start. Humans are crazy, and a subset of us enjoy pushing past the boundaries merely to prove that it is possible to ourselves. To prove that we have no limits. I think those people should be given every opportunity that humanity can afford to give them to push the limits of human capability.
