Long Term Survival is mostly about knowing inherently what you can and cannot survive

 What do I mean by this?

It's that you have to be in touch with your instincts and intuition to survive.

For example, something like a Mountain lion knows it cannot survive being injured so it is very careful even though it is a really powerful animal. So, survival for a big cat has to do with being especially ruthless in that they wait up in a tree so that they can jump on the back of an animal or person and bite them in the back of the neck before they are seen by anyone.

I'm not saying humans are like this at all but if you think you can take infinite physical injuries and keep going basically you can't. This is why so many people who are boxers or kick boxers who get hit in the head too much are gone by the time they are 30 or 40 because either they physically fall apart or they mentally are so gone they can no longer work and take care of themselves.

So, life is not only about being physically strong it is about being mentally strong too.

And without both things people are often soon gone and that is the end of them unless they have someone strong and healthy mentally and physically to take care of them.
