"Goodbye to all my dear friends and family that I love. Today is the day I have chosen to pass away with dignity in the face of my terminal illness, this terrible brain cancer that has taken so much from me ... but would have taken so much more. "The world is a beautiful place, travel has been my greatest teacher, my close friends and folks are the greatest givers. I even have a ring of support around my bed as I type. Goodbye world. Spread good energy. Pay it forward!" This was 29-year-old terminal cancer sufferer Brittany Maynard's final message before she took medication to end her life under Oregon's "Death with Dignity Act".
