Cat
Cats occupy a curious position regarding necessity. No human requires a cat for survival. Food acquisition, shelter maintenance, and social functioning all proceed perfectly well without feline involvement. The cat provides nothing essential to human existence in the purely material sense.
Yet cat ownership correlates with measurable health benefits: reduced cardiovascular risk, lower cortisol levels, and improved mental health outcomes. The non-essential cat somehow proves essential to wellbeing, a paradox that speaks to human needs extending beyond mere physical sustenance into domains of companionship and purpose.
USB Cable
Modern existence requires USB cables with non-negotiable urgency. Device charging, data transfer, peripheral connection: these fundamental activities demand functional cables as absolutely as lungs demand oxygen. The absence of a working USB cable renders thousands of pounds of technology immediately useless.
This necessity carries corresponding vulnerability. The forgotten cable transforms a productive journey into a battery-anxiety nightmare. The failed cable at a critical moment generates consequences ranging from inconvenience to professional catastrophe. USB cables have become infrastructure as essential as electricity itself, their importance inversely proportional to their reliability.
