Life span

Life span - also known as life expectancy or life cycle - was the amount of time an organism was expected to live based on its time of birth and other factors.

Prior to first contact with the Vulcans, the human life span was typically just under a century, or 100 standard years. By the mid 23rd century humans could live well past the age of 100. . In the 24th century Leonard McCoy lived well past the age of 137. .

The maximum life span of the Klingons was something of a mystery as many Klingons died violent deaths while still young. However many Klingons lived well over a century. .

At the other end of the spectrum for humanoid life spans, the Ocampa only lived about nine years.
