Your Spine & Nervous System
Your brain, quietly floating in your skull, appears to be doing nothing, yet it processes billions of bits of information about what’s going on, in and around you, every moment and sends out billions of commands: how fast your heart should beat, blood chemistry changes, blood pressure, how to throw a football, bake cookies and what to wear.
