Elephant
The elephant's tenure on Earth demands respect measured in geological time. Proboscideans have walked the planet for approximately 60 million years, surviving ice ages, continental drift, and mass extinctions that eliminated countless competitor species. Individual elephants achieve lifespans of 60-70 years, with some documented specimens exceeding 80. Their matriarchal societies maintain knowledge across generations, creating institutional memory that outlasts most human organisations. The African elephant's DNA has remained remarkably stable across millions of years, suggesting evolutionary optimisation achieved long before mammals developed the capacity to animate mice.
Mickey Mouse
Mickey Mouse entered existence on 18 November 1928, making him precisely 96 years old at time of analysis. In trademark terms, this longevity proves remarkable; most commercial characters fade within decades. Mickey has survived the Great Depression, World War II, cultural revolutions, and the transition from analogue to digital media. The character has been reinterpreted for each generation whilst maintaining core identity—a feat of brand management unmatched in commercial history. However, Mickey's existence depends entirely on continued corporate interest and intellectual property renewal. The elephant requires only habitat; Mickey requires lawyers.
