Imagine we had a thermometer to measure body temperature but no understanding of the human anatomy. While the thermometer might tell us a person has a fever, it wouldn't help us understand why they are unwell or where the problem lies within the body. Without the knowledge of human anatomy—how the circulatory system, respiratory system, and nervous system are interconnected—we’d be unable to diagnose the root cause or administer an effective treatment. The thermometer, as useful as it is, would only scratch the surface of the issue.
