WiFi
WiFi's durability is a study in paradox. The technology itself has proven remarkably resilient, evolving through six major generations whilst maintaining backward compatibility - a feat akin to a Victorian telegraph machine seamlessly connecting to a 5G network. The underlying protocols have survived floods of data traffic, security breaches, and the existential challenge of smart refrigerators attempting to send firmware updates.
However, individual WiFi signals display all the robustness of a soap bubble in a hurricane. Concrete walls, microwave ovens, fish tanks, and the mere presence of too many neighbours can reduce a robust connection to digital whispers. The technology's durability, therefore, is conceptually eternal yet practically fragile.
Wolverine
Wolverine's durability is, quite simply, the gold standard of fictional indestructibility. His mutant healing factor allows recovery from wounds that would reduce ordinary organisms to historical footnotes. Combined with an adamantium-laced skeleton - a metal so durable it exists purely within Marvel's imagination - Wolverine can survive nuclear explosions, decapitation, and being torn in half by the Hulk.
The character has canonically survived for over 130 years, regenerating from injuries that violate several laws of thermodynamics. His durability is so extreme that writers regularly struggle to create meaningful threats, resulting in increasingly absurd scenarios designed to temporarily inconvenience an essentially immortal being.
