"Many people treat their bodies as if they were rented from Hertz - something they are using to get around in, but nothing they genuinely care about understanding."  Become a student of the human body...particularly your own!  Remember:  You are the CEO of your health...how can you make educated decisions if you don't understand the basics of even 'your' health?  The road to mastery begins now...a lifelong process of learning!  Have the best day gang!
