We fear being murdered, kidnapped, raped and assaulted by strangers, when it's far more likely
that the perpetrator of such offenses is a relative or a friend. We
worry about airplane crashes and rampaging shooters instead of
automobile crashes and domestic violence -- both far more common. In the United States, dogs, snakes, bees and pigs each kill more people per year (.pdf) than sharks. In fact, dogs kill more humans than any animal except for other humans.
