Dementors are loosely based on the symptoms of depression, and 24 other Harry Potter facts


Did you know that Harry Potter and J.K. Rowling share the same birthday? That's just one of the 25 facts about the Potterverse in this week's video from our sister site, Mental Floss.

And Rowling is the first person to ever become a billionaire from book writing. Check out all of the facts, which cover trivia from both the books and the movies, in the video below, hosted by author John Green. --Meghan DeMaria
