<<There are many modern conviences that take their toll.  Cars produce
exhaust.
 Diesel fuel (or its exhaust?) has been recently shown to BE
carcinogenic.
Every chemical on every surface in your house is suspect, along with
the
chemicals you use to clean them.  Teflon pans left on a stove
unattended
kill
birds instantly.  Every bird breeder knows that.  (I'm a bird
breeder.)
That
can't be healthy.  There are hundreds of suspects.>>

I agree.  And I minimize them in my environment, and treat others who
suffer
the ill effects of this.  But, I eliminate exposure everywhere I can.
Why
add insult to injury?
