Re: The Sad Case of the Patient Protection and Affordable Care Act
A nice illustration of this in one figure:
It appears that you misunderstand life expectancy.
Life expectancy is different at different ages (and also is different depending upon which mortality table you use...). The life expectancy of someone in their 40s is to a later age than the life expectancy of someone in their 20s because some of those 20-year olds have died along the way to 40.
According to the IRS life expectancy table used to calculate required minimum distributions from retirement plans, the life expectancy of a 65-year old is 20 years. The life expectancy of a 75-year old is 12.5 years (IRS Table V).
That table is probably a bit out of date these days. I read an article recently that asserted that the fastest-growing age cohort in the US is ages 90-99. The news shows used to make a big deal over people turning age 100; they've stopped because so many people are living past 100, it's no longer newsworthy.
