Being ready for a week-to-month long disruption is always a good goal, and we're there ourselves. However, true end-of-world survivalist preparations are not much use to the large part of the American population that now depends on monthly deliveries of critical medicines. Without delivery of insulin, cardiac medicines, etc., all else quickly becomes irrelevant. That was a quite discouraging revelation, when Hurricane Ike shut down most SE Texas pharmacies for a couple of weeks.
Personal health is a big part of survival and while anyone of us can get sick knowing how to take care of yourself, eat right, exercise and think right is the crux of survival. Pharmaceutical companies have a ring through everyone's nose just like energy and agri-business. Learning how to exist without those forces is true independence and freedom.
People should be thinking about those things regardless what happens with the world. People here are talking about meat but I'll tell you it's not the best food for health. Read a book called "The China Study". What you want to eat are green leafy vegetables and lots of them. Anyone here go to the doctor and get told to cut down on their fruits and vegetables? I'll bet not! That should be the core of your diet if you want to be healthy.
