So the vast majority of posters on here intend/would want to kill themselves. In reality, how many people actually do that in old age? Very very few. Because whatever we think when we're well, we're primed to stay alive, even when we're old and life isn't great.
My mum always said she wouldn't want to live if she got ill or very old. Then she had a massive stroke and is largely helpless, paralysed down one side. For the past 12 years she's been a nursing home, and now an extra care facility.
When she got an infection in the nursing home, she got very ill, and wasn't conscious. The nursing home didn't have a DNR in place, so they asked my brother, initially, what she'd want. He didn't hesitate at all and said she wouldn't want to be resuscitated. I confirmed that when they asked me.
My mum recovered, and then the nurse at the home asked her what she'd want should such a situation happen again. Foolishly she mentioned what my brother had said. My mum was furious, and said that she wanted everything done to keep her alive. And 10 years on she still tells people my brother wants her dead.
She's in her late 80s and still occasionally needs to be hospitalised. Every time, the doctors ask her about resuscitation, and every time, sometimes to their obvious discomfort, she says she wants everything doing.
She has done a complete 180 degrees change of mind. When you're well, you think the life you might have in old age will be awful. When you're actually in that position, you might well find that at least it's life and you don't want to give it up.
