Comment: While poorly cited (although virtually all information is gathered from two listed sources) and while I haven't been involved with the page for several years, going back through seven years ago, the page has been premised on verifiability. While it is indeed unlikely the Monsieur Huysmans is precisely the 69th longest lived state leader, he is indeed the 69th (+/- a few, at most) longest-lived leader listed on worldstatesmen or rulers (the two preeminent sites in lists of leaders) "whose age can be proven beyond reasonable doubt" via sources on his (and other leaders') pages. More or less, this means that this is as complete a list as can be compiled, and covers ~90%+ of leaders (the remainder being unverifiable Asian/African leaders) over the past two centuries, before which it was exceedingly uncommon for individuals to surpass the minimum age of entry (95+ years). As per WP:N, "there is no present consensus for how to assess the notability of more complex and cross-categorization lists (such as "Lists of X of Y") or what other criteria may justify the notability of stand-alone lists, although non-encyclopedic cross-categorizations are touched upon in Wikipedia:What Wikipedia is not," Wikipedia:What_Wikipedia_is_not#Non-encyclopedic_cross-categorizations|which refers to, e.g., "people from ethnic / cultural / religious group X employed by organization Y" or "restaurants specializing in food type X in city Y," neither of which are anything close to this list. WP:N states that "lists that fulfill recognized informational, navigation, or development purposes often are kept regardless of any demonstrated notability," the first of Wikipedia:Manual_of_Style/Lists#Purposes_of_lists|which is broadly defined as a "list that may be a valuable information source. This is particularly the case for a structured list. Examples would include lists organized chronologically, grouped by theme, or annotated lists." Do what you like, but WP's rules seem to leave room for this page, and the nominator's comment is essentially WP:ATA |USELESS
