Darwin did not say it's the strongest and smartest who survive. He said it's those who best deal with change. Local emergencies will bring small changes but national or global disasters will bring big changes. Will you shrivel up and die without gas, groceries and gadgets? There's a time in the life of every problem when it's big enough to see but small enough to fix, and not being prepared is a problem you can solve now. Acquire the supplies, skills and mindset of a survivor, not a victim.
