I think that some very valuable questions have been asked here, and it brings to the forefront, questions that many on FR will have to deal with, whether for their loved ones or for themselves...
Decisions that need to be made when one, or their loved ones are very ill should be carefully considered...
Each case will be different, the circumstances of each case will be different....you cannot take what happens in one case, and think that it applies to another case...
My husband had a friend whose wife died, because she decided to stop dialysis...she found it quite unbearable to endure the dialysis, as it was not greatly improving her quality of life, and she just felt it was not worth the time and pain it caused her...she had a husband and four sons...the sons were all teen-agers, and certainly hated to see their mom make this decision, but they also understood the great pain and distress she was in, as they witnessed it every single day...so she stopped her dialysis, and within a few weeks she died...but during those few weeks she remained alive, she and her husband and her children, made the very most of the time remaining, and when she died, nothing was left undone or unsaid between all the family members....
Now, that was her choice, others will chose differently...
As I said, each and every case is different...
I agree... and thanks for your example :~)
