Sort of.

Yes, the nobility and the royals basically had comparable lifespans to those today.

The average peasant? Wikipedia so grain of salt, but it lines up with much of what I have seen over the years en.wikipedia.org/wiki/Life_expectancy.

Life Expectancy at Birth (LEB) in the Bronze age is believed to be around 24. Now, this is going to be skewed because we are generally finding the sites of battles (easier to find 20 corpses than 1…). But, at the same time, LEB in the medieval period (30-33) is going to be skewed by most records caring a lot more about the nobility than some rando on a farm.

LEB has 100% gone up as wars become less common and medicine becomes much more effective and plentiful. And I’ll admit I was exaggerating for comedic effect here. But also… not that much.

Because maybe you DO have good odds of living to your late 50s if you make it to your early 40s… the average is low for a reason and it isn’t JUST infant death. It is working hard to survive day to day and being incredibly vulnerable to crop yields (whether starving or being sent to war because said nobility got hungry/bored). And when you are seeking knowledge from those more experienced around the village… they are gonna skew a lot younger than Lord Farquad’s uncle.
