"The Deadly Years" is a second-season episode of the original science fiction television series Star Trek, first broadcast December 8, 1967 and repeated on August 16, 1968. It is episode #41, production #40, written by David P. Harmon, and directed by Joseph Pevney. This episode explores the question of whether advancing age is a relevant reason to remove someone from a position of authority. It is shown that, while one's physical abilities may be hindered by aging, the mental faculties are often as sharp as they ever were; indeed, the experience of age oftentimes more than makes up for mental acuity. In this episode, strange radiation exposes the command crew of the Enterprise to the effects of rapid aging.
