The 25th Amendment — codifying protocols for when a president dies or is unable to serve — wasn’t even ratified until 1967. That was after Dwight D. Eisenhower had suffered a major heart attack, which left him recuperating in Denver for several weeks in 1955. (His press secretary first reported it as indigestion before coming clean). It was also after John F. Kennedy was assassinated, a sharp reminder of presidential mortality. In life, Kennedy presented an image of healthful vigor, but “his ailments were legion,” says Barbara Perry of the University of Virginia’s Miller Center, which studies the American presidency. Among them: Addison’s disease, crippling back pain, colitis — not to mention a physician nicknamed “Dr. Feelgood” who prescribed the president amphetamines.
