Dr. Andrew Lyne:

To explain, suffering at the time of dying is quite a complex issue. Looking at the data from Canada - part of the reason we reference Canada is that it gave us a lot of data - and the reasons people there were motivated to die, the two most common reasons were that they were not able to live life in a meaningful way and that they were not able to do activities of daily living. Activities of daily living include being able to dress yourself, being able to go to the toilet by yourself and being able to feed yourself. That was quoted by over 80% of people who requested assisted dying in Canada. That type of suffering is not readily amenable to medical intervention all of the time.
