I had the advantage of learning some things from my son who is the documentary film maker and filmed one of the major survivor guys on TV, there with him in the wild for those films, and another one for several episodes in Africa and the Amazon, plus son being in those places has to be able to save himself.
One has to realistic and not see it as a fun game or think it is a breeze for it isn't.
I am reading and laughing... surviving is a piece of cake, but having fun doing it might take a little planning!
1965 Boy Scout Handbook? I read that and laughed. My Girl Scout Handbook is about 1940! LOL I did do 18 hours in a snowstorm and built a small snow shelter...didn’t get cold but keeping face dry with drifting snow was the hard part.
