Growing Up Bin Laden

I'm currently reading Growing Up Bin Laden. It's fascinating reading. Omar bin Laden, Osama's fourth child, reveals that his father was always very serious in his demeanor and demanded it of his sons as they were growing up. The senior bin Laden discouraged the drinking of water in an effort to make his sons tough and shunned all modern conveniences, except for cars, especially fast ones. The book is coauthored by Osama's first wife and by Jean Sasson.
