Health stories you may have missed. 🎃

ICYMI Health features what we're reading this week.

This week, in honor of Halloween, our colleagues across HuffPost explored the science of our most commons fears and how we can overcome them.

We were also captivated by a frightening article about extreme sleepwalking, a sleep disorder that can result in the sleeper turning violent without any knowledge of his or her actions.

And on a disturbing note, we spent time with a story about the role of identity politics on the war on drugs in America, and how, as an increasing number of white middle-class families are torn apart by heroin, the conversation and punitive laws surrounding drug addiction are changing.

People who exhibit violence during parasomnia are not behaving with full awareness or intent. But while intent is relevant in the courtroom, it probably doesn’t matter to the person on the receiving end of the axe.

The surging heroin crisis among middle-class white white Americans is changing the country's language and legal approach to drug addiction, which also points to troubling racism.

When the nation’s long-running war against drugs was defined by the crack epidemic and based in poor, predominantly black urban areas, the public response was defined by zero tolerance and stiff prison sentences. But today’s heroin crisis is different.

Atlantic editor James Hamblin interviews the people trying to diversify our protein sources beyond animal meat -- creating sustainable alternatives from from peas, soy nuts and even bugs.
