  One of the great challenges of lattice QCD is to produce unambiguous
predictions for the properties of physical hadrons. We review recent progress
with respect to a major barrier to achieving this goal, namely the fact that
computation time currently limits us to large quark mass. Using insights from
the study of the lattice data itself, together with the general constraints of
chiral symmetry, we demonstrate that it is possible to extrapolate accurately
and in an essentially model independent manner from the mass region where
calculations will be performed within the next five years to the chiral limit.
