Here is a trustworthy saying that deserves wide acceptance: Most of the people who blather on about other people's "quality of life" have never actually lived. I used to be scared to lose my mind, to get Alzheimer's, or some other dementia. But you know what? I don't need my wits; I just need my joy. And if I have no consolation from the gospel, my faith is enough. Faith proclaims what is true, even if it has no companions. If people say of me, "He believed, and he loved, and therefore, he lived," then it'll be a good life, no matter what I suffer at its end.
