Query: Good study of worst case scenarios and how to survive them

I enjoyed the storyline approach to survival tactics. The book plays out various do-or-die situations and the characters survive them. I kept a list of things that I would like to add to my survival cache as I read through the book.After reading the book, I feel like I have returned to a state of bliss with our current freedoms and lifestyle. I will never complain about the price of gas again and I enjoy each trip to the grocery store. It is nice to have fresh vegetables in the middle of winter.I hope we never have to survive worst case scenario, but I feel this book gave me a better basis for facing it if I have to.
