evidence: Already the longest-lived of the 45 men to serve as U.S. president, Jimmy Carter is about to reach the century mark. [...] That boom has not reached Plains, where Carter has lived more than 80 of his 100 years. His wife Rosalynn, who died in 2023 at age 96, also was born in Plains. [...] Carter has lived through 40% of U.S. history since the Declaration of Independence in 1776 and more than a third of all U.S. administrations since George Washington took office in 1789 — nine before Carter was president, his own and seven since.
