Cat
The domestic cat demonstrates remarkable structural resilience. With an average lifespan of 12 to 18 years under optimal conditions, individual specimens provide extended service periods far exceeding most household acquisitions. The skeletal system incorporates approximately 230 bones with flexible cartilage connections enabling survival of falls that would incapacitate less sophisticated organisms.
Self-repair mechanisms operate continuously. Minor injuries heal without intervention. Fur regenerates following damage. The immune system combats pathogens with reasonable effectiveness, though veterinary maintenance remains advisable. Unlike mechanical systems, the cat does not suffer component obsolescence, continuing to function on original biological hardware throughout its operational lifespan.
French Fries
French fries exhibit durability characteristics best described as catastrophically limited. From the moment they emerge from hot oil, degradation commences immediately. Optimal consumption window spans approximately 7 to 12 minutes before textural collapse renders them objectively inferior. No preservation method has successfully extended this timeline whilst maintaining acceptable quality standards.
Cold french fries represent one of humanity's most documented disappointments. The crisp exterior that defined their appeal transforms into a leathery membrane of regret. Interior starch structures solidify into waxy configurations that resist both teeth and dignity. No amount of reheating restores original characteristics, a limitation that has resisted all technological intervention.
