👉 "A rusty backed old bicycle is like a human's life after a particularly nasty skirmish with a rusty old car - it's sturdy on the outside, but utterly useless on the inside. Imagine someone who's been through a war, fought off every rusty backside of a pick-up truck, and now rides this contraption because it's still got wheels, even if its chain is more like a broken promise than a promise keeper."
And here's a sentence to really drive home the point: "The detective's rusty backed intuition led him straight to the suspect, but when he finally caught his breath and looked in the mirror, he realized he was staring at a man who'd just been chased by a rusty old dog."
