Tea
Properly stored tea maintains palatability for decades or even centuries. Pu-erh teas from the 1950s command prices exceeding $10,000 per kilogram, their flavour profiles enhanced by time. The tea plant itself proves remarkably resilient, thriving across diverse climates from Himalayan slopes to Scottish highlands. Archaeological evidence confirms tea consumption four thousand years ago, with the tradition remaining essentially unchanged. The plant survives frost, drought, and pruning with admirable persistence.
Wolverine
Logan's adamantium skeleton renders him functionally indestructible by conventional means. The metal alloy bonded to his bones cannot be dented, scratched, or melted by temperatures below the sun's core. Combined with his healing factor, Wolverine has survived nuclear explosions, drowning, decapitation attempts, and being buried alive. He has existed since 1832, aging at imperceptible rates, potentially capable of living indefinitely. Even when his healing factor was temporarily suppressed, his adamantium skeleton remained pristine.
