Longevity

Longevity is the ability to live for extended periods of time, well beyond a natural life span with a slowed aging process. In most cases, the aging method shows very little to no degree at all.

Kryptonian's Longevity
Due to the success of living in a sustainable atmosphere with little to no complications, a Kryptonian’s body can remain in the same physical state for as long as possible. This can enable them to live well into their hundreds to even thousands of years with every detail of their appearance remaining unchanged. It is believed that their physical appearances reach the peak of their lives in the range of their twenty years (on Earth). Usually female Kryptonians can vary from their teenage years (16-21), and males (22-25). However those that have aged being in their natural atmosphere and have only arrived in new terrain can only have their aging suspended where they already are.
