Oldest Living State Leaders

This is a list of the Oldest Living State Leaders, and it is comprised of 100 long-lived current and former heads of state. Incumbents will be shown in bold italics. This list is straight from the Wikipedia page of the same name. Here is the Wikipedia page. Those past 100 in italics will ascend when others in the list die. Note that for some unknown reason, since leap day, the days calculations have been 1 day off, so when calculating age, add an extra day to the number of days presented (only until their next birthday).
