Of course, this prosperous career path has its risks. You'll be outdoors a lot, and Mars's atmosphere is pretty thin, so cosmic radiation could fry your DNA. Things could fall on you on construction sites. And you'd probably go prospecting alone (why split the profits?), so no one could help you if you got lost or fell into a crater. You could play it safe in the colony, working at the Spacemart. But you're on Mars—take a chance!
