Google is starting a new project which aims to extend our lives. These efforts are always popular. So are efforts to study people who live 110 years, such as Dan Beuttner's book Blue Zones.


What is left out of the equation every time are the very old people who are only partially fixed, the people who have new joints and a pig's valve or two but who can't function due to Alzheimer's disease. Or people who are ready to die but can't because their heart just keeps on going. Again, quality of years is just as important as quantity.
