" Fear was the
worst thing. Fear would put her at the mercy of whatever misfortune
came. Even the wild beasts could smell fear on your body and would
come and attack, while they would flee from the courageous. This
was why the bravest man could run among the deer with safety, so
long as fear was not smelled on his skin "

― Marion Zimmer Bradley , The Mists of Avalon (Avalon, #1)
