This came to my attention the other day. Last Friday, George H. W. Bush became the longest-lived president in U.S. history, at 93 years, 166 days. He bested Gerald Ford — who isn’t getting any older — that day, and topped Ronald Reagan about a month and a half ago. Reagan had the longest-lived distinction for a few years in the early 21st century, and more recently, for about the last 10 years, Ford was the oldest.
Presidential longevity is reaching new heights here in the 21st century. For a very long time, about 175 years, John Adams was the longest-lived president. He famously died on July 4, 1826, aged 90 years, 247 days. Reagan passed him only in 2001.
Now each of the four presidents who followed Richard Nixon have lived to be at least 93, with the elder Bush and Jimmy Carter currently gunning for 94. To reach 93, George W. Bush and Donald Trump would both need to live to 2039; Bill Clinton, to 2040; and Barack Obama, to 2054.
