Human Body & Mind

The human body is a universe unto itself — 37 trillion cells working in concert, an electrical storm of consciousness flickering inside three pounds of neural tissue, and a immune system that wages silent wars every second of every day. We carry within us more mysteries than all the textbooks in the world have managed to explain. From the dreams that visit us at night to the gut feelings that guide our decisions, the most extraordinary frontier of discovery isn't out in space — it's right here, beneath our own skin.

"The brain is wider than the sky."

— Emily Dickinson
