TED Talk: Paul Zak - Trust, Morality and Oxytocin

~ Dr. Paul Zak has devoted himself to understanding how we feel trust and morality through Oxytocin released in our brain. I must confess, I am an Oxytocin addict. I am a regular user, I make eye contact often and am fond of hugging my friends and family. I sing, dance and pray readily; all of these are great sources of this marvelous endorphin. Paul Zak researches real world scenarios and how oxytocin plays a role in our happiest moments. In short, he recommends a minimum eight hugs per day to maintain emotional well being. So get out there and hug those lovely people in your life.
