Mailvox: No fear!

Big Chilly sends word of an incredibly courageous woman who puts us all to shame:

“SM has been studied for more than 20 years, and many papers have been published about her fear-related abnormalities. She has trouble recognizing fear in facial expressions, for example. In another experiment, published in 1995, she was blasted with a loud horn every time she saw a blue-colored square appear on a screen. Despite the repeated blasting horn, she never developed the fear an ordinary person would feel when seeing the blue square.

Emphasis is mine. She not only does not, but can not fear seeing the blue square. Holy crap.
