“Some age” doing a lot of work here. Yeomen in 14th Century England who made it to 20 years old still had a life expectancy of just 48-52 (depending on when in the century).
Life expectancy is mean not median, and the median wouldn’t work like that either.
Of course, some people loved to 70, I think there would be virtually no circumstances where that would be expected (ignoring ad absurdum takes like “age 69 and 364 days”)
