Everyone knows what it is to be afraid.

But phobias take the normal (and even helpful!) human emotion of fear to a much more visceral, even primal, place. For some people, it’s a spider that does it. For others it’s a clown, or a trans-Atlantic flight, or even just a puddle of water. It’s the thing that stops us in our tracks, sets our hearts racing, and stands our hairs on end. Scared Stiff takes readers on a journey through these experiences—using biology, psychology, and history (not to mention pop culture) to explain where our phobias came from, how they affect us, and how we might eventually overcome them.
