I think you misunderstood the person you're replying to. They meant that people's lives should end well (not propped up on life support) and that we should focus more on quality of life than on life extension. There was a great article that went around a few years ago called "How Doctors Die"[1] that showed the difference between medical professionals approach death and how normal people approach it.
