Love
Love's longevity predates recorded history. Archaeological evidence suggests pair bonding behaviours extending at least 3.5 million years into human evolutionary history. The phenomenon appears to be hardwired into mammalian neurobiology, ensuring its persistence regardless of cultural or technological change. Love existed before agriculture, before writing, before the wheel. It will, researchers confidently predict, outlast current civilisations and potentially the species itself, as similar bonding mechanisms exist across the animal kingdom. Love is not merely old; it is functionally immortal.
Wolverine
Wolverine's personal longevity is impressive by human standards. Born James Howlett in 1832, the subject has survived nearly two centuries, maintaining physical capabilities equivalent to a man in his prime. His healing factor theoretically grants indefinite lifespan, barring complete cellular destruction. However, Wolverine exists as a character only since 1974, when Roy Thomas and Len Wein conceived him. As intellectual property, his existence depends on corporate decisions, audience interest, and legal frameworks. The character could theoretically be discontinued at any moment, whereas love's existence requires no such institutional support.
