There is no single term for when people don't age, as this is a concept found in fiction and mythology rather than in reality. However, there are several terms and concepts related to the idea of immortality or agelessness:
Immortality:
- Immortality is the ability to live forever, without aging or dying from natural causes. This concept is often explored in literature, mythology, and fantasy.
- Biological Immortality: Refers to the ability of an organism to avoid death from aging. This is different from immortality, which implies an eternal lifespan.
- Examples: In mythology, figures like the Greek god Zeus and the Norse god Odin are considered immortal. In fiction, characters like Dracula and vampires are often portrayed as possessing immortality.
Agelessness:
- Agelessness is a state of not appearing to age, even though time passes. This can be a result of genetics, lifestyle choices, or even fictional magic.
- Examples: Some people are genetically predisposed to age more slowly than others. In fiction, characters like Peter Pan are depicted as eternally young.
Other Related Concepts:
- Eternal Youth: Refers to the state of being perpetually young, often associated with beauty and vitality.
- Longevity: Refers to a long lifespan, but not necessarily eternal life.
It's important to note that while these concepts are interesting, they remain in the realm of fantasy and fiction. In reality, all living organisms age and eventually die.
