set up in nitrogenous matter--protein-bearing foods, but
particularly animal foods. Endogenous toxins are autogenerated. They
are the waste products of metabolism. _Dr. John. H. Tilden, Impaired
Health: Its Cause and Cure, 1921._

Suppose a fast-growing city is having traffic jams. "We don't like

there are uncoordinated traffic lights and because almost all the
businesses send their employees home at the same time. Easy to fix!
And no reason whatsoever to limit the number of cars. The asphalt

fit the existing roads? Tax gasoline prohibitively, pass out and
give away free bicycles in virtually unlimited quantities while
simultaneously building mass rail systems? What? Which?

When we settle on a solution we have simultaneously chosen what we
consider the real, underlying cause of the problem. If our chosen
