Let’s assume your food source was cut off. Given the current state of your in-house larder and the current occupants, how long could you survive without being dangerously hungry?
I’m considering all usable foodstuffs in the house – frozen, canned, dried, and/or in a root cellar. You have electricity and/or gas for cooking, no heat or cooling problems. You have a water source, so you can make bread if you have flour & yeast; you can open a can; you can raid your root cellar for potatoes, onions, and tomatoes. But you can’t visit a supermarket, milk a cow, dig a carrot, or pick anything from your trees or harvest from your garden.
How long could you last without major suffering?
