It’s not about the specific year though, it’s just that the average life expectancy includes infant and child mortality, which used to be a lot higher in most countries. This pulls down the average but there were still plenty of people who lived to 50-60. Our upper life expectancy is higher now, but not 50 years higher.
i’m just gonna generalize this to “any year before 1600” and edit the title
