I asked my PT how many muscles in the human body. As I worked on my injuries I felt some new ones. There are between 650 – 840 muscles in the human body. Most of us only are aware of (and use) a few. Sad, but the nose can detect 1 trillion odors, and 27 categories of the six basic emotions. We each have 100 billion brain cells featuring 100 trillion connections. We were meant for a lot more than fighting, sex, eating, chasing coins and doing nothing; no matter what they say.
