Just a slight correction to the above - caloric restriction is only one
of a variety of techniques which extends life span.  One should include
protein restriction (Bruce Ames), tryptophane restriction, and methionin
restriction.  This latter is probably unrelated to caloric restriction,
since the energy intake of the met restricted animals (rats) was equal
to or greater than in controls.
