Very few cave men have been found that died of old age.

You can know every skill required, know every eatable plant and every hunting and trapping skill ever devised and get caught by a freak storm, falling tree branch or slide down a ravine and break a leg and be dead like Fred.

Of course you could, I think we all know that,... but its not answering the question

I would have though that someone with your experience could come up with a more informative answer
