I am very, very much in favour of having the right to choose when we feel our time should be up.
The only real arguments against it seem to be (A) religious ones - and no-one will have to go along that road if they do not wish to do so (B) ensuring proper and careful checks and regulations are in place - and that is imperative, but can be done.
I have no fear of being dead - to me it is the end - I have and have never had any sort of religious believes, or thoughts of heaven, valhalla, or anything else.
I do have a very (and increasingly as I get older) fear of the manner of my dying. Yes, I have a strong Advance Declaration in place, Yes, my children (all with similar believes), no my wishes - but still am scared.
Surely, I should be given the right to decide when I feel it is time to leave this life - and to be able to do so with dignity.
My chosen way is at home, having had time to say all my goodbyes, ensured my affairs are in good order - then having a Doctor give me a drink which will quickly send me to sleep and total sleep.
I would expect there to be a longish and very careful period between my first asking for this and for it being carried out, during which I would be checked to ensure it is MY decision totally, and I knew and understood what the decision meant.
New Zealand, without doubt, seems to be the world leader in so much these days.
