Longevity

Summary
Longevity is the ability to age far more slowly than any normal being, allowing the user to have a lifespan that far exceeds any human, sometimes reaching hundreds or thousands of years if not longer. Unlike Type-1 Immortality, beings with Longevity do age, and thus will weaken over time and may die of natural causes if they are not killed first, however long this process may take.
