Longevity
Longevity was the ability to live longer than the average life span for a species.
In the 1st millennium BC, there was a mass eugenics program on the planet Sahndara. Individuals were bred for contemplation, self-reliance, and longevity. The number of individuals generated by the program was pared down to thirty-eight. This group was later discovered by the USS Enterprise in 2268 on the planet Platonius. (TOS: "Plato's Stepchildren")
