Here's another juicy one: In 1987, more than 8,000 dogs bit humans in New York City, while there were 1,587 reported instances of a human biting a human in the Big Apple. That same year, there were 13 shark attacks in the entire United States [source: ISAF]. Statistically, it would seem that a person was more likely to be bit while riding the New York City subway than swimming in the ocean.
