Forget about Iran for a second.
Why not worry about the kind of things you can find in your own kitchen, like the microwave. Or why not worry about the kind of things you strap to your head, like bluetooth wireless phone ear pieces or cell phones themselves. Or why not worry about the cancerous cells currently being formed inside your body thanks to the invisible faxes being sent wirelessly around you all day long?
Yes. Why not worry about those things instead of Iran.
