  Single band theories of quantum criticality successfully describe a
single-particle lifetime with non-Fermi liquid temperature dependence. But,
they fail to obtain a charge transport rate with the same dependence unless the
interaction is assumed to be momentum independent. Here we demonstrate that a
quantum critical material, with a long range mode that transmutes electrons
between light and heavy bands, exhibits a quasi-linear temperature dependence
for {\it both} the single-particle and the charge transport lifetimes, despite
the strong momentum dependence of the interaction.
