Maybe you know that current freshmen in high school are learning about 9/11 as a historical event. They can't answer the question "Where were you when 9/11 happened?"
Or maybe you know something about the human body that's both random and bizarre, like how babies are born with over 90 more bones than they'll have as adults.
