A big record was broken today among U.S presidents, and it has nothing to do with North Korea. John Adams lived to age 90, and so did Herbert Hoover more than a century later. Ronald Reagan made it to 93, as did Gerald Ford, who for a while became the oldest living former president in history. No U.S president has ever made it to his 94th birthday, until today. Happy 94th to President George H.W. Bush! Jimmy Carter will of course join him later this year.
