Where do you get this figure? According to wikipedia, modern HG live about 40 years from age 15. Numbers I’ve seen from the paleolithic are similar, but much less precise. I think Caspari-Lee and Trinkhaus both expect the median paleolithic adult to reach 45.
I went by memory. But anyway, if the total life expectancy at 15 was about 55, it would still be the case that they would have been disproportionally less subject to old-age diseases than we are.
(and anyway, modern hunter-gatherers are generally at least neolithic, not paleolithic)
