  We present a simple picture that provides the energy and scattering length
dependence for all inelastic three-body collision rates in the ultracold regime
for three-body systems with short range two-body interactions. In particular,
we present the scaling laws for vibrational relaxation, three-body
recombination, and collision-induced dissociation for systems that support
s-wave two-body collisions. These systems include three identical bosons (BBB),
two identical bosons (BBB'), and two identical fermions (FFF'). Our approach
reproduces all previous results, predicts several others, and gives the general
form of the scaling laws in all cases.
