“...human beings have a distorted view of risk. They don't see the whole picture. Our perceptions are twisted by stories in the media, by films, by our own personalities and experiences. So, despite the unlikely odds, we still worry about being raped or murdered. We hear a sound in the night and think of burglars, not mice... It's kind of a protective pessimism: if we worry about the worst happening, it may miss our door.”
