Avocado
Archaeological evidence suggests Persea americana has been cultivated for approximately 5,000 years, with wild ancestors dating back considerably further. The fruit has outlasted empires, survived ice ages, and adapted to climates from tropical to Mediterranean. Individual specimens, however, face a notable limitation: the 48-hour ripeness window that has frustrated consumers since antiquity.
Gandalf
As a Maia spirit, Gandalf's existence predates the creation of the physical world itself—a timespan measured not in millennia but in cosmic epochs. His current form has wandered Middle-earth for approximately 2,000 years, whilst his essential being has persisted since before the Sun itself was kindled. Even death proved merely a temporary inconvenience, resulting in an upgrade from Grey to White.
