Joanne Tubbs Kelly and her husband, Alan, had talked hypothetically about their support for laws like Colorado’s End-of-Life Options Act, but they never knew it would be a choice they’d have to make. That changed when Alan Kelly was diagnosed with a terminal illness and decided he wanted to take advantage of the law. The book, "Walking Him Home: Helping My Husband Die with Dignity,” by Joanne Tubbs Kelly, is about that experience.
