I have always assumed that what Joe said is the case, but then my question
is, "why does comparing nuclear workers with other similar workforce cohorts
become fuzzy?"  Isn't that really the comparison we should be making in the
first place?  Why is it not the normal case as Russ indicated he assumed it was?
