For those of you living in a country-type area, then mass-canning for 2 years etc. is probably a good bet because your food supply will be at less risk from the hungry population as it would be for the rest of us who live in the city. But, if you are stuck in the city, i believe you are better off using your intelligence to devise a peaceful means of ending your life with as little suffering as possible, rather than a slow starvation. Because a 2 years food supply in a city-house will simply get given out to all your neighbours, or it could be taken by force if they find out about it. Still going to buy some bags of rice, canned fish,etc. to last a month or so, but that is all.
