  Anomalous metallic properties are often observed in the proximity of quantum
critical points (QCPs), with violation of the Fermi Liquid paradigm. We propose
a scenario where, due to the presence of a nearby QCP, dynamical fluctuations
of the order parameter with finite correlation length mediate a nearly
isotropic scattering among the quasiparticles over the entire Fermi surface.
This scattering produces an anomalous metallic behavior, which is extended to
the lowest temperatures by an increase of the damping of the fluctuations. We
phenomenologically identify one single parameter ruling this increasing damping
when the temperature decreases, accounting for both the linear-in-temperature
resistivity and the seemingly divergent specific heat observed, e.g., in
high-temperature superconducting cuprates and some heavy-fermion metals.
