Not really a surprise to me, but I'm kind of a natural prepper, I'm the child of 2 parents who were wartime children so always behaved as if a crisis were imminent mainly to save money as we were never very well off. I grew up in the countryside so learnt how to forage, how to light a fire, gut fish and animals, skin or pluck them etc, we grew veg, had chickens etc, my mother pickled everything that didn't move and veg was preserved for over the winter, I can make clothes, knit, repair shoes and do all sorts of stuff that probably is largely irrelevant in day-to-day life mostly.
At present, I am making jams etc for the winter so will have around 20+ jars in various flavours, usually from whatever marked down fruit is available, the herbs that grow in the garden I'll dry and jar, stale bread is blended to make dry breadcrumbs which can be used in cooking. We have a lot of dried beans stockpiled, rice, tinned food. My husband works for well-known chemists so we have a year's worth of toiletries which we replenish each October when they have a double discount offer. We have a garden which right now is tomatoes, cucumber, salad, beans, peas and loads of other stuff including chillis and garlic. You can freeze margarine, UHT milk or milk powder (buy rennet and you can make cheese), salted cod is good too as it lasts and other tinned fish.
We have a good first aid kit and essential is the first aid manual, so you know what to do if you're not a first-aider.
I'm probably a bit obsessive but so is DH, DSS thinks we are a bit tin foil hat, but I remember how my parents and grandparents were and they managed to survive the war years so I don't think they were entirely mad. You can at least save yourself some money if it's all ok and nothing very much happens.
We do have the option to head to the continent as DH is EU and that is a possibility, but even there money won't grow on trees and we'll carry on as we are anyway!
