I wonder if I might just go off track for a little? There is another side to this, a friend whose daughter had learning difficulties, not severe, but bad enough to need constant supervision, was found to have stomach cancer which was at a stage when it could be treated. Because it was appreciated she could understand what was happening, it was necessary for her to sign the consent form for an operation - she was of that age - but refused to do so on several occasions, and eventually died. I have been told there was nothing that could be done about her refusal, but I am not absolutely sure on the fact. I do know however that she was a very determined young lady, and quite aggressive on occasions.
