Half the defective smoke detectors
being over ten years old may be due to other causes:

* They came from dirty homes and the dust-bunnies interfered with proper
operation. It's a fact that half the homes in America are dirtier than the
median.
* Ten years ago, there was a big influx of Chinese smoke detector circuitry
made with Melamine.
* ALL of the failed smoke detectors had their batteries removed to eliminate
the nagging chirp.

Or: Half the smoke detectors in use are over ten years old.


It's poor practice to make decisions based on assumptions about cause and
effect.

My thesaurus sez poor practice = idiotic.


If one gets exercised over the "ten year = failure" business, here's an even
more shocking revelation: Virtually ALL of the failed smoke detectors were
colored white!

Damn those defective white smoke detectors. Why isn't the gummint doing
something about it???


Beware.
