Alone's later seasons got more diverse- it was fascinating watching how people cope given that we are in fact a social species who mostly live in groups (and even those who live in remote areas tend to have at least some contact with other humans). It was also interesting seeing how quickly things could go badly wrong - a slip on a slope and you are effectively disabled and at risk of sepsis and starvation.

Have you watched/read Into the Wild and the associated commentary at all? One of the most apt things I've read is that successfully surviving in any environment is a learned skill (and involves a degree of luck) - you're either taught it by your parents/older people or you learn it as you go, but it's certainly not innate, and it's a lot easier to learn by being taught.
