Longing for Season 5?

One thing I find interesting is thinking about everyone you know and then imagining everyone on a island. Who would love the setting, survive and flourish, who would hate the situation, act irrational, and self destruct. The most intriguing piece about this scenario is that some would do well based on their mental capacities, others drawn from experiences, and some just on physical strength. I imagine this and think about the Ironman, because an Ironman race would claim anyone who didn't excel in all three.
