ATLANTA - Weeks shy of his 95th birthday, former President Jimmy Carter said he doesn't believe he could have managed the most powerful office in the world at 80 years old.
Carter, who earlier this year became the longest-lived chief executive in American history, didn't tie his comments to any of his fellow Democrats running for president in 2020, but two leading candidates, Joe Biden and Bernie Sanders, would turn 80 during their terms if elected.
Biden is 76. Sanders is 78.
"I hope there's an age limit," Carter said with a laugh as he answered audience questions on Tuesday during his annual report at the Carter Center in Atlanta. "If I were just 80 years old, if I was 15 years younger, I don't believe I could undertake the duties I experienced when I was president."
Carter's observation came in response to a jovial inquiry about whether he had considered running in 2020 since he's still constitutionally allowed another term. The 39th president left office in 1981 at the age of 56 after losing his reelection bid to Ronald Reagan, who served two terms and left office as the oldest sitting president in history, at 77.
Either Biden or Sanders would be older upon their inauguration than Reagan was on his final day in the Oval Office. At 73, President Donald Trump is a record setter, as well. He eclipsed Reagan's mark as the oldest newly elected president in history and would become the oldest president to be reelected. Age has been a flashpoint for some critics of Trump, Sanders and Biden.
Carter, who turns 95 on Oct. 1, said the Oval Office requires a president "to be very flexible with your mind," particularly on foreign affairs. He was speaking on the 41st anniversary of the Camp David Accords, a peace agreement he negotiated with Egyptian President Anwar Sadat and Israeli Prime Minister Menachem Begin.
"You have to be able to go from one subject to another and concentrate on each one adequately and then put them together in a comprehensive way, like I did between Begin and Sadat with the peace agreement," Carter said.
"The things I faced in foreign affairs, I don't think I could undertake them at 80 years old," he continued, before adding with a smile: "At 95, it's out of the question. I'm having a hard time walking."
