  We use low energy optical spectroscopy and first principles LDA+DMFT
calculations to test the hypothesis that the anomalous transport properties of
strongly correlated metals originate in the strong temperature dependence of
their underlying resilient quasiparticles. We express the resistivity in terms
of an effective plasma frequency $\omega_p^*$ and an effective scattering rate
$ 1/\tau^*_{tr}$. We show that in the archetypal correlated material V2O3,
$\omega_p^*$ increases with increasing temperature, while the plasma frequency
from partial sum rule exhibits the opposite trend . $ 1/\tau^*_{tr}$ has a more
pronounced temperature dependence than the scattering rate obtained from the
extended Drude analysis. The theoretical calculations of these quantities are
in quantitative agreement with experiment. We conjecture that these are robust
properties of all strongly correlated metals, and test it by carrying out a
similar analysis on thin film NdNiO3 on LaAlO3 substrate.
