Sloth
Individual sloths enjoy a respectable lifespan of 20 to 30 years in the wild, with captive specimens occasionally reaching 40. More impressively, the sloth family has persisted for 64 million years, surviving the asteroid that eliminated the dinosaurs, multiple ice ages, and the rise of humanity. The giant ground sloth, Megatherium, stood six metres tall and roamed the Americas until approximately 10,000 years ago. The Palaeontological Society of Leeds notes that sloths have outlasted 99.9% of all species that have ever existed.
Football
Modern football has existed for approximately 160 years, a mere blink in evolutionary terms. Yet the sport shows no signs of decline. The International Federation of Football History projects continued global growth for at least the next century. However, predicting human activities beyond this timeframe requires optimism regarding humanity's continued existence that palaeontologists find touching but naive. Football's long-term survival depends entirely upon the survival of the species that invented it.
VERDICT
The sloth's 64-million-year track record demonstrates staying power that football cannot yet claim. When the last football is kicked, descendants of today's sloths may still be hanging from branches, moving imperceptibly through whatever remains of the rainforest, having outlasted yet another of humanity's enthusiasms.
