#10. Can Pets See Ghosts?
Owners of dogs will have noticed that, if you provide them with food and water and shelter and affection, they will think you are god. Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods. —Christopher Hitchens What does the quote have to do with ghosts, aside from the fact that some studies show a healthy correlation between religious beliefs and ghost beliefs—in

#9. Shedding a Little Light
It happens a lot. I get an email or text, or I’m chatting with someone at a party or a group hike. They tell me about a supernatural experience they had, or an impossible coincidence they read about, or some unearthly thing that happened to a friend of a friend’s niece.

No, it’s something a lot more urgent and insidious: Sharks! Scientists have discovered a strong statistical link between ice cream sales and shark attacks on humans along coastal waters.
