Some interesting things to read and watch.

Listen to a doctor talk about drugs (illegal drugs) and their true effect on their brains.
Watch a series about asthma in New York and also a news segment about asthma in the Bay Area.

I hope you can open this. It's a provocative interview on KPFA, listener-sponsored radio. The person being interviewed is Dr. Hart, a neuroscientist at Columbia. He wrote a book called "High Price: A Neuroscientist's Journey of Self Discovery".
