If you read carefully the big factor is suicide and drugs, and "
increased deaths amongst younger and middle-aged individuals (particularly those
between 24 and 44) had an outsized effect on calculations.
As Kathryn McHugh of Harvard Medical School tells
NPR’s Richard Harris, “We're seeing the drop in life expectancy not because we're hitting a cap [for lifespans of] people in their 80s, [but] because people are dying in their 20s [and] 30s.”
Since I'm past 20s and 30s and don't do drugs (overdose) and don't intend to suicide, I feel my lifespan is longer than the old average.
Note: Since SS does not discriminate based on sex, and women even with old calculations lived to the 80's , it seems a slam dunk women claiming on their own earnings would delay until 70.
