Does the human heart compare to the engine in your automobile?
My Toyota has 276,000 miles on it. Everything is original. I change the engine oil every 7,000 miles, as stated in my auto’s manual. Each time, before leaving, I let the engine run for about one to two minutes. This lets the oil circulate to crucial engine parts, just like the human heart and its blood. I give credit to my engine’s long longevity and maintenance-free performance, to the two minute warmup period. Question: how does the human heart compare to the engine in your automobile? How are they alike?
