Okay, one needs plenty of things. But without knowledge one does not know what to purchase. However there are books ... plenty of them. I have couple books about survival: Aguirre, Fernando: The Modern Survival Manual: Surviving the Economic Collapse. Buenos Aires, 2009. ISBN 978-987-05-6345-7. Luther, Daisy: The Pantry Primer: A Prepper's Guide to Whole Food on a Half Price Budget. Milton Keynes, 2015. ISBN 978-1-5089-5280-0. Do you know books to recommend?
