What are some examples of misconceptions?

Misconceptions are beliefs or ideas that are incorrect or misunderstood. For example, many people think that lightning never strikes the same place twice, when in fact, it can and often does. Another common misconception is that humans swallow an average of eight Spiders a year while sleeping, which is unfounded and highly unlikely. Additionally, some believe that goldfish have a three-second memory span, whereas studies show they can remember things for months.
