  The applicability to dense hard sphere colloidal suspensions of a general
coarse-graining approach called Record Dynamics (RD) is tested by extensive
molecular dynamics simulations.
  We reproduce known results as logarithmic diffusion and the logarithmic decay
of the average potential energy per particle. We provide quantitative measures
for the cage size and identify the displacements of single particles
corresponding to cage breakings. We then partition the system into spatial
domains. Within each domain, a subset of intermittent events called quakes is
shown to constitute a log-Poisson process, as predicted by Record Dynamics.
Specifically, these events are shown to be statistically independent and
Poisson distributed with an average depending on the logarithm of time.
Finally, we discuss the nature of the dynamical barriers surmounted by quakes
and link RD to the phenomenology of aging hard sphere colloids.
