Microwaved Nuts (FPOTW)

Critical thinking skills.
Sadly, such skills are not taught in class or in school.
There was a time when the ability to think critically would help ensure survival. Now, medical advances keep dumbasses alive long enough to procreate.
Critical thinking has gone out the window.

Cell phone radiation! I know several people who will absolutely not carry their cell phone in their pockets for fear of irradiating their nuts.
"I want to have children some day!" they cry.
Some people are dumb enough to drop a small fortune on an air acoustic headset for their cell phone, so that the microwaves do not travel up the headset wire and irradiate their brains.
Humm... balls or brains... quite the tossup on what to nuke.

A few simple numbers for consideration:

Average maximal cell phone power is about a Watt.

Cell phones transmit at a frequency of about 800-900 MHz. Call it an even GHz.

To cause a chemical reaction, a couple of eV are needed. To ionize a molecule, a few eV are needed.

The average human body produces about 100W of power.

---- Fermi Problem ----

Estimate how much you will raise the temperature of your left nut (if you don't have one, substitute your right ovary) if you were to dump a Watt of energy into it over a period of an hour.

Calculate the energy of the incident microwaves in terms of electron volts.

Estimate how many people think that microwaves are only good for cooking their food.

---- End Fermi Problem ----

Of course, high tension power lines are another matter... I mean just look at the grass under them! The grass is taller under the wires than away from the wires. If you don't believe me, just ask the row of birds sitting on the wires.
