There are down sides though. For some reason Sebaceans cannot survive in temp. of 85F to 90F or higher for very long. Under such conditions they enter what they call the Heat Delirium, which seems to be a degradation of the nervous system. The last phase is a persistent vegetative state, that all Sebaceans fear. also while smarter than humans they seem to have less mental flexibility and adaptability. but that could be cultural.
