:Well I'll be a monkey's uncle. That will teach me to simply assume definition from prefixes! However, is supercentenarian a necessary attribute of a given nation's recordholder? (See discussion above regarding artificial limitations to this list.) Perhaps we should remove the language about supercentenarians altogether, as it would seem that several countries may not have recordholders that have achieved the age required for such a distinguished title. [Perhaps this whole thing will also teach me to get heavily involved in articles on subjects that I am so disinterested in. *sigh* Probably not, though.]
