President Joe Biden, 80, is officially running for reelection, and if successful, he will be 86 at the end of his second term. Polls show an overwhelming number of Americans think he’s too old for the job and shouldn’t run again; calls are also intensifying for 89-year-old Dianne Feinstein to step down from the U.S. Senate, amid ongoing concerns regarding her cognitive health and exacerbated by a prolonged bout with shingles that has found her unable to perform many of her duties, most notably help confirm federal judges in her role on the Senate Judiciary Committee.

Some say it’s time for a mandatory retirement age from Congress, others are
calling for presidential candidates to take a mental competency test. But we each
age differently, and one person’s 80 is another’s 60. How old is too old? Is there
such a thing?
