Dr. Stephen Duckworth:

I do not think that one can. I have a fantastic quality of life. I have numerous jobs, I have four children, I have a beautiful wife and a love life. That is my autonomous position on my current state of being. However, should that dip below a certain threshold for me, although I love what I do and I do what I love, I would not love dying in intolerable pain. At that point, I would like to have access to that service. In terms of autonomy, it is up to each individual to die but I would only accept it on the basis of the grounds of someone having a terminal illness diagnosis of six months or less, which is commonly used in practice in the UK to evaluate people's entitlement to certain disability benefits.
