Surely that can’t be true? Life expectancy is going up all the time so why would somebody who is already 80+ today be expecting to hit 91 when a newborn is only going to make 81?
Of course it's right. Well, it's right that not everyone who is 82 today is about to drop dead imminently.
I'm not going to waste my time trying to explain it to someone who lacks both the logical reasoning and mathematical ability to go "Ah yes, of course!", so I googled https://www.google.com/search?clien...ncy+longer+when+they're+old&ie=UTF-8&oe=UTF-8
I got this page: https://www.verywellhealth.com/understanding-life-expectancy-2223950 - it may help.
