Avocado
The avocado's durability presents a study in fragility that borders on the philosophically tragic. A specimen may remain stubbornly unripe for seven to ten days, then achieve perfect ripeness for a mere twenty-four to forty-eight hours before descending into brown mush. Its skin bruises upon gentle contact. Once sliced, oxidation begins immediately, turning the verdant flesh an unappealing brown within minutes. Cold storage merely delays the inevitable decline.
Thor
As an Asgardian, Thor possesses a lifespan measured in thousands of years. His physical form has withstood direct exposure to the power of a neutron star, repeated combat with the Hulk, and the existential trauma of watching his entire civilisation destroyed. He has survived Ragnarök itself—the prophesied twilight of the gods. Even accounting for narrative convenience, his baseline durability exceeds that of most known materials in both the scientific and mythological catalogues.
