With all the discussion of EMPs lately I`m curious what will NOT be damaged... and what can be done to limit the damage or eliminate EMP damage totaly.

Will flashlights work?
Will ALL cars be broke or just ones with computers?

If things do stop working is it perm. or temp? If both (which is my guess) how can you tell which items will die for good, and which you can plan to use in case of an EMP?
