Right-to-die advocate Brittany Maynard ended her life on Saturday, activists close to her family confirmed Sunday night, NBC News reported. The 29-year-old drank a lethal mixture of water, sedatives and respiratory-system depressants — a move she had been planning for months to escape the final stages of terminal brain cancer. She had set Nov. 1 as the tentative date for her death. Maynard was diagnosed with a fatal brain tumor in April and moved to Oregon to access the state's "Death with Dignity" law, saying that she had no intention of allowing the disease to control how she lived, or how she died. "It is people who pause to appreciate life and give thanks who are happiest," she told her family before her passing. "If we change our thoughts, we change our world! Love and peace to you all."
