After comparing the physical roles of thermal pair annihilation of non-relativistic particles in QCD and in cosmology, I discuss the tools that can be used for estimating this rate, either perturbatively or through lattice simulations. Subsequently it is illustrated how in strongly coupled systems, bound states may give a large contribution to the thermal pair annihilation rate, even if model details matter quite a bit here.
