You can’t eat money (or gold)
Some people may find the above link useful. If/when the shit hits the fan remember that all your investments and money will be wiped out - even if you think you're covered by compensation schemes if your bank goes bust you'll probably be looking at a minimum of SIX MONTHS before that compensation comes through - that's six months during which time you'll have no access to your money, for what it's worth.
Maybe you've got gold? Better, but what you'll really need is a roof over your head, food, and water. These are the important things.
Please take care of yourselves and your families. Use the above guide to plan yourself a rolling inventory of food stocks to keep you going through hard times.
