The idiom "running on fumes" means to be in a state of exhaustion or extreme fatigue, often due to lack of sleep, poor diet, or overexertion. It can also refer to being out of energy or stamina, feeling drained or depleted, and lacking the ability to perform at one's usual level.
The origin of the idiom "running on fumes" is unclear, but there are several theories as to how it came about. One theory suggests that it comes from the early days of automobiles when cars ran on gasoline and would eventually run out of fuel, leaving drivers feeling drained and depleted. Another theory connects the idiom to the ancient practice of sacrificing animals to appease gods and spirits, where the animals were often run until they were near death or collapse, leaving people feeling exhausted and depleted. Over time, the meaning of the idiom has remained relatively consistent, but its usage has varied depending on the context. For example, it can be used in a positive context to describe someone who is pushing themselves to their limits and needs some rest, or in a negative context to describe someone who is exhausted and unable to perform at their usual level.
