I think the point still stands. In the Paleolithic era, life expectancy for the 60% reaching age 15 averaged 39 remaining years [1], so you could have expected to live into your mid 50s, compared to mid 80s today in developed countries [2]. That's a 30 year difference, so it's more than "a bit smaller".
