Our brains run off chemicals.  Some of these chemicals like Dopamine and Serotonin make us happy.  Even if we are doing destructive things.  As social creatures we get brain chemical buzzes from being in like-minded groups, even if those groups are not winners.   THE GREATEST ADDICTION IS NOT DRUGS OR ALCOHOL, BUT THE ADDICTION TO OTHER PEOPLE'S LIMITED OPINIONS ABOUT YOU AND YOUR LIFE.   Dr. Fred Clary, founder of Functional Analysis Chiropractic Technique and lifting/life coach/ gym-chalk covered philosopher opens a conversation on the greatest addiction in your life; other people's opinions.
