Middle age rule
(sh.itjust.works)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
To be fair most people who live to the average life expectancy do live past it, the average gets skewed down by people dying in car accidents in their 20s and such like.
Eh demographics shows a grim tale. People start really dying around 65 and it accelerates pretty quickly into the next few decades. Very few people live to be 100. About half of an age cohort will make it to 75. A quarter will make it to 85. This is easily visible on demographic charts.
