Pagan Stances on Euthanasia?

I’m curious about something. There have been a few news articles recently about euthanasia and assisted suicide. I know the Christian position of Just Say No, and I’ve read comments various places by people whose religions were not specified about going through the dying process (or living with an untreatable illness) as necessary for spiritual growth or working off karma etc. (Although I have some doubts about how much spiritual growth someone is going to accomplish when kept alive against their will—or with dementia.) So I was wondering if any of the various pagan religions had a viewpoint on this. Is there a religious duty to go on living until the bitter end? What about non-terminal illnesses, and where do you draw the line? Or is it entirely the choice of individuals?
