“Hysterical, disturbing and fundamentally true.”

The 5-year-old nose picker in me delighted in Cutter Woods’s attention to all things gross in EARTHLY MATERIALS, while my adult sensibilities reveled in his eminently-readable research of the infinitesimal miracles and machinations of the human body. A must read for popaholics, blood donors, the pee drinking community, and anyone who’s ever been amazed or aghast at what just came out. 

Rachel Yoder, Author of NIGHTBITCH

With a flair for storytelling, Wood pulls unexpectedly profound insights from deeply strange anecdotes. The result is an utterly unique tour of the human body.
