Rust on machines is like scars on our skin. It is a reminder and it is a sign of what we've been through and that nothing is eternal. Nothing we can do about it, just accept it. It is the way of life, older gets obsolete and will be cast aside to make space for newer and better leaving us on a walk down the memory lane wondering that why was grass greener and the sky bluer when we were young. I feel like a rusting away sometimes, but there's a bright side to it - we can now annoy younger people the way our elders used to annoy us with their endless smarts and knowledge.
