RJ's definitions apply here as well, in my opinion.
Certainly we are all going to die, but that doesn't mean the cessation of life any sooner, when one is in fine physical condition, isn't rooted in being emotionally unstable or mentally unbalanced. Emotions can play a terrible trick on us, by convincing us we are ready for something of which we have no intellectual grasp beyond the most rudimentary elements. Hindsight is 20/20 unless you are no longer alive. Then there's no regretful changes of heart. The ultimate finality of death is why this issue has to be handled so carefully.
Preventing death, it is not the same thing as prolonging life. We are too hung up on the former. So much so that we lose sight of the latter, sometimes even working against the latter INHO.
Say you have a man, he's 80 years old and in perfect health for a man his age. He is retired, his family is secure, he's happy with his life. You are saying he shouldn't be allowed to choose to end his life then, when he wants and how he wants with all his family around (supporting his decision) together. He should be treated as a mental patient and forced to continue living a life he feels has reached it's natural end simply because Death is wrong? He should be forced to waist away for another ten or twenty years, a life really of existing nor living, just because people are hung up on the issue of death? Wouldn't that be the near the same level of mental torture, spread out over a greater time, as someone with a terminal illness?
Your premise that once you reach a certain age you start to "waste away" is false to begin with. Some people are healthier in their 70s and 80s than they were in their 20s and 30s. If your hypothetical 80-year-old is in good physical condition and has no chronic ailments impacting his life, why would he want to die?
It would be different if he had some kind of incurable, progressive disease slowing eating away at him. But you seem to be implying that once you reach a certain age you inevitably start to lose everything, and that's just untrue.
I understand your point about not prolonging life just to escape death, but you seem to have gone too far in the other direction--that we should think it's OK for an otherwise healthy and fit person to off themselves just because they're "finished" with life. Someone who has had a good life and is enjoying themselves and isn't on death's door is not going to have that attitude; it means something is wrong.
i agree ;especially if the person is healthy and can still enjoy life. heck through most of her 80's at least till 86 my mother was having a good time with friends ect.
and she had health issues.
you never know when you are going to meet an interesting new person, hear a beautuful new piece of music , see a grandchild born.
