Former President Jimmy Carter said Wednesday at an event at the Carter Center that he hopes for an "age limit" on the presidency, saying he couldn't do it at age 80.
"I hope there's an age limit," said Carter, who started his term as president at age 53 and is now 94. "You know, 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. For one thing, you had to be very flexible with your mind. You have to be able to go from one subject to another, concentrate on each one adequately and then put them all together in a very comprehensive way."
Elizabeth Warren is 70 years old. President Trump is 73. Joe Biden is 76. Bernie Sanders is 78.
