When Brittany Maynard was diagnosed with a virulent brain tumor, she investigated what might help her and how the end would look if nothing helped. What she learned about how that end would likely unfold scared her more than anything. She searched for a way to stay in her home state of California and still experience a gentle, pain free death when the time came. But there was none. With the support of her husband, Dan Diaz, and the rest of her family, she made the wrenching decision to move to Oregon in the last months of her life so that she could take advantage of the Oregon Death With Dignity Act, which allows terminally ill people the option of ending their life with medication. After her death, Dan became a fierce advocate for the End of Life Option Act in California and similar acts across the country. Although the California act went into effect, it is under attack and has been suspended. How is Dan affected by the grueling process of trying to fulfill his promise to Brittany?
