"Buy agricultrual land or something you can run a couple of sheep and grow some vegies. only this will matter in the future (you are right) when the world collapses."
When the world collapses the outlaw gangs will come after your land, your veggies and your sheep. If you want to prepare yourself for that event go to live for a while among an aborigine community in central Australia with plenty of know-how about how to survive in the bush. But do not learn how to make fire as smoke can attract undesirable people even in the bush.
