I agree with SPG, medical care is a 'modern' concern but in much of the world medicine is a meager effort and many people still live to a reasonably elderly age.
Security would be my biggest concern, if those electronics zombies can't text or tweet a thousand times a day what will they do? Many of them will lash out until things settle down. That is assuming a fast crash scenario, in a slow crash there are way too many variables to be able to even guess what the biggest concern should be. If you don't have three months or more food on hand you are not planning for any kind of trouble, you are just assuming the local grocer will always have what you want or need right when you want or need it.
