My Apocalypse Survival List

This is information that I have gathered from books, shows, movies and from experience (Not in the apocalypse, but I think you get the point). If you are serious about this, please research on your own.
I will try to include where I found the information but at times I truthfully don't know how I know these things, I think of them as common knowledge (I come from a prepper family).
Please comment tips and suggestions, if you notice I am missing something or you just remembered an important thing we should know.
And remember, when you survive, watch your back, be kind to others but not too kind, stay hidden but be known, you have to live and you have to thrive.
