22. The possibility that nonrelativistic systems inconsistent with the strong KSS bound may have no consistent ultraviolet completion was suggested by Dam Son (private communication).

25. D.T. Son (private communication) has pointed out that it may be possible to apply the bound indirectly for ordinary fluids. The idea is to construct a quantum field theory with electrons and fundamental fields for nuclei and with electromagnetic interactions which look like those in the standard model and therefore yield essentially the same fluid properties. However, it is unclear whether such a theory can be found which is both well defined and yields absolutely stable fluids.
