There is a very large gradient. Even all of those symptoms, while lower quality of life than when they were in their prime, are a far cry from being in a hospital/nursing home, with random people poking needles into you all the time, and that is a best case scenario. I know from seeing my grandparents, who lived into upper 90s. At home, they were still happy. Being poked and prodded in a hospital is a material step down in quality of life. On top of that, imagine having a breathing tube/catheter/etc.
