Check out this blog post by Bill Peace (Bad Cripple) on the Brittany Maynard story. In the comments, Bill writes:

“She will knowingly end her life before she becomes disabled. Thus her stated desire to die is indeed about disability. By logical extension she assumes end of life will involve disability and that sort of life has no value. Statistics from Oregon and Washington clearly demonstrate people do not end their life because they are in pain. The loss of autonomy and fear of being a burden to family are the primary reasons people end their life. I will also disagree over pain. There is no need for people to die in pain. Top notch pain control…via hospice care is routine and effective.”
