When the next U.S. president is sworn in on Jan. 20, 2021, he will be the oldest person ever to take the oath of office. Donald Trump, if reelected, will be 74 years old; if it’s Joe Biden, he will be 78. (The previous record was set in 1985, when Ronald Reagan was inaugurated for his second term three weeks before turning 74.)
Both candidates have been raising concerns about the other’s fitness, relying on common tropes about age and disability; Trump’s campaign has even depicted Biden in a wheelchair as an elderly and disabled potential resident in a senior home, while Trump himself has taken heat for problems with walking up and down ramps.
