George H.W. Bush had a birthday yesterday, and at 94, he is the oldest living former president in history. None the other men who've held the office ever reached the age of 94. You are forgiven for thinking that Jimmy Carter was older, since he served earlier. The record brought up other tidbits about presidential ages in the comments at reddit.
Funnily enough, Bill Clinton, George W. Bush and Donald Trump (elected over a span of 24 years) are all the exact same age. Each is 71, having been born in 1946. Clinton was the third youngest person to ever become president; Trump was the oldest. And Bush, at 54, was incredibly close to the median age for presidents at the start of their term, which is 55 years 3 months.
In other words, over the course of just nine weeks in 1946, three different presidents were born. They would go on to be elected in three different decades (and maybe four). One would be one of the youngest ever elected, one would be the oldest ever elected, and one would be elected at precisely the typical age. -IRAn00b
John F. Kennedy was the youngest person ever elected president at age 43, Teddy Roosevelt was the youngest to become president, at age 42, after McKinley was assassinated.
Jimmy Carter is only 4 months behind him. Born: October 1, 1924 (age 93 years) -samtheotter
Somewhat unrelated, but California Governor Jerry Brown is both the youngest California governor since the 1860s (elected at age 36) and the oldest ever (72 years old when he began serving his current term). -jlux999
Until the 2000s, the president who lived the longest was John Adams. The second president. -solidsnake885
John Adams was 90 when he died in 1826.
