Lion
Wild lions rarely exceed fifteen years, with males averaging closer to ten due to their exhausting lifestyle of territorial combat and looking magnificent. The Botswana Mortality Studies Group notes that lion lifespans have remained remarkably consistent throughout recorded observation, suggesting evolution has settled on 'brief but glorious' as the optimal configuration.
Even in captivity, with veterinary care and regular meals, lions seldom reach twenty-five.
Hope
Hope has existed since the first organism experienced a setback and somehow continued existing. Archaeological evidence from the Oxford Intangible Antiquities Department suggests hope predates written language by approximately two hundred thousand years.
More remarkably, hope appears to be immortal. It survives personal tragedy, systemic failure, and every January gym membership that goes unused by February. The Edinburgh Persistence Research Centre has never recorded a verified instance of hope permanently dying, though it occasionally takes extended holidays.
VERDICT
While lions measure their existence in years, hope operates on a civilisational timescale. Even extinct cultures left behind artefacts suggesting they believed things might improve. Hope wins this category by several geological epochs.
