Reality emerges from a mutually coupled
(enslaved) system of DNA and its
environment

SO!
Is Aging, per se,
A Disease?

“Aging and disease
are not
synonymous. There
are processes of
aging and
etiologies of
disease. The
relationship
between the two
are important, but
not inevitable”
Nathan Shock, Ann. Rev.Physiol. 1961

“... to draw a
distinction
between disease
and normal aging
is to attempt to
separate the
undefined from
the undefinable”
J.G. Evans, Research and The Aging Population 1988
