I began this thread because I wanted to know what you folk are thinking on this issue. Thanks for expressing those thoughts.
Personally I view life as sacred and a precious gift from God. He is Lord over life and death. Therefore, I oppose suicide.
I also find it painful to think of elderly people coming down to the end of their lives and having their loved ones view their existence as a burden. That is profoundly sad. Nonetheless, not every relationship between parent and child (children) is characterized by love and care. Often that is the parent's fault. So, for better or worse, the aged will have to deal in the end with the relationships that they have nurtured over the years.
Whenever possible the elderly should have made provision so that their end of life care will not be a financial burden upon their children. I understand that love does not pay bills. Parents should lay up for their children, not the other way. The emotional and physical burden is another thing. It is a price that love extracts, hopefully willingly.
I am opposed to extraordinary means simply to sustain existence when there is no prospect of recovery. A living will is a necessity. Dr. C. Everette Koop wrote a helpful book many years ago titled The Right to live, the Right to die. I commend it highly.
