What It Means: America’s Gerontocracy

The back-to-back inaugurations of presidents aged 78 reflect a shift toward a more gerontocratic leadership—a term describing rule by the elderly. Critics have warned that advanced age can raise questions about the physical stamina and mental acuity required for the presidency. Recent debate has centered on both Trump and Biden’s health and fitness following public slips, minor health concerns, and questions about mental sharpness.
