Myths and misconceptions are widely held beliefs that are often false or exaggerated. They can arise from cultural stories, misunderstandings, or outdated information. For example, many people believe that goldfish have a memory span of only a few seconds, when in fact, they can remember things for months. These inaccuracies can lead to confusion and misinformation. It's important to critically evaluate claims and seek reliable sources to distinguish between fact and fiction. By doing so, we can better understand topics like health, science, and history, and avoid being misled by popular but incorrect ideas.
