Do vampires really exist? Are they one more thing to worry about?
It depends on whom you ask.
Vampires have long been a part of the folklore of certain areas, particularly in parts of Eastern Europe. Made famous in modern times by Bram Stoker's Dracula, vampires were portrayed as horrific characters who terrorized the townspeople, rising at night to suck the blood of their victims, thus turning the victims into vampires, too. Stories also exist of people having witnessed the aftermath of a vampire attack.
Nowadays, books, movies and TV are filled with vampires and werewolves, and some, such as Twilight's Edward Cullen, are even sympathetic characters. On this date in 1997, Buffy the Vampire Slayer premiered on TV, mixing wit, teenage angst and B-movie drama in a popular series about a high-school student who is chosen to slay the vampires that inhabit her town.
