""Fear is primal. Raw. Blood pressure increases. Veins in your skin contract. Your immune system shuts down. Even if you attempt to steel against fear... it is undeniable. Fear makes us human. That was the conclusion of Charles Darwin. Who am I to argue? I'm a man of science, too. A psychologist. But few know my academic achievements. If you know me at all, you know me as... the Scarecrow." - Green Lanterns #17"
