I'd love to hear what anyone has to say about this .. as I struggle with the same thing with my parents. I have found that the only somewhat 'peace' I can have is if I leave them alone about it, accept that they're going to do it and respect their wish to do so. I don't want to spend their remaining years nagging them constantly about it -- even if it's done out of love. They are my parents, after all.

I am sure every situation is different -but if anyone has tried something that worked in their case, I too would love to hear about it.

Thanks for posting this question... it's been on my mind to do so lately.
