On October 1, 2021 James Earl Carter Jr (born October 1, 1924) became the first US President to celebrate his 97th birthday. On March 22, 2019 he became the longest-living US President when he crossed the mark set by George Herbert Walker Bush.

He passed one more landmark on October 17, 2019 when his marriage to Rosalynn became the longest-lasting of Presidential unions. (See update at end). They were married on July 7, 1946. They will cross the record of 73+ years of George Bush Sr (again!) which ended with Barbara’s death on April 17, 2018.
However, Rosalynn Carter (born August 18, 1927) is now 95 and has some time to go before she can overtake Bessie Truman (97, 1885-1982) as the longest-lived First Lady. In the past few years, She overtook others such as “Lady Bird” Johnson (94), Betty Ford (93) and Nancy Reagan (94).
There is, however one Vice-President who has lived longer than any President: John N Garner (98, 1868-1967, VP to Franklin Roosevelt in 1933-41).
Joseph Biden (20 Nov, 1942) is the oldest person to become President surpassing Ronald Reagan’s 73+ at the start of his second term in 1985. Donald Trump (born Jun 14, 1946) was so far the oldest to become President for the first time at 70+, just edging out Reagan’s accession in 1981.
Meanwhile, Queen Elizabeth II (born April 21, 1926) continues to break longevity records as the longest-lived British monarch (93+) with the longest reign (67+ years). Her consort Prince Philip died about two months before what would have been his 100th birthday.
As pointed out earlier here, Queen Elizabeth’s reign has seen 14 US presidents (Truman to Biden) and 15 British PMs (including Harold Wilson twice). It is likely that she will see the successors of the present incumbents.
