Lincoln Miles is the owner of Europe's only shop for "preppers" - people who are fixated on surviving the end of the world.
The shop sells everything from crossbows to clothes designed to help people survive in the case of nuclear disaster.
The Victoria Derbyshire programme's Benjamin Zand went on a tour.
