  We point out that the recent discussion of non-relativistic AdS/CFT
correspondence has a direct application in non-equilibrium statistical physics,
the fact which has not been emphasized in the recent literature on the subject.
In particular, we propose a duality between aging in systems far from
equilibrium characterized by the dynamical exponent $z=2$ and gravity in a
specific background. The key ingredient in our proposal is the recent geometric
realization of the Schr\"{o}dinger group. We also discuss the relevance of the
proposed correspondence for the more general aging phenomena in systems where
the value of the dynamical exponent is different from 2.
