When we legislate we need to know that there is accuracy attached to the terms. If we are asking doctors to make a declaration or statement of prognosis, they must at least know that there is some scientific basis behind it. In making a decision, there are three fundamental issues; first, the person must have accurate information; secondly, they must have the mental capacity to make that decision; and, thirdly, it should be voluntary and free of coercion. If you make the decision to end your life because you believe that what lies ahead in the next weeks and months is so terrible but, in reality, you might have improved dramatically and lived for years if you had had the care you needed, then I would say that you are not being supplied with accurate information and that it is therefore not a valid decision.
