Although this is interesting, it frustrates me that “additional average life expectancy” is featured so prominently. I think it’s a metric that’s outgrown its usefullness. When life expectancy was growing like mad over the past 100 years, it was useful. Now its growth isn’t so dramatic. The real questions are:
- Do we really want to live as 90 year olds for as long as we can?
- Should we really keep people alive so that we don’t even know who’s dying anymore?
We should be focused more on “additional happiness expected after age 65.” Unfortunately, that’s too waffly for the doctor and statistician types.
