Great strategy for choosing the Title :D Nice writing style as well.

I would only like to further emphasize the difference between the microwave oven and cell phone. While the microwave oven is closed and keep all the microwaves inside, mobile phones/ radars etc. are used in the open spaces and their irradiation is much less "concentrated". Even if you take something like a 1000 phones - it will not boil anything, unless there is some box surrounding them.
