Life expectancy and median age (didn't find average but I assume it is pretty close) were the first things I checked when I read your comment, but life expectancy globally is in the 70s and the median person about 30. I don't understand how the average person could have only a little more than 10 years left.
Some people might be minutes away from death, dragging the average way down. And the youngest of the adults alive right will probably not live more than 60-70 years max. And there’s a lot more old people right now than younger people due to increasing healthcare standards. It’s possible.
