What was that humans average lifespan in the 1200s?

In the 1200s, the average lifespan of humans was significantly lower than today, typically ranging from 30 to 40 years. However, this average was skewed by high infant mortality rates; many children did not survive past infancy or early childhood. Those who did reach adulthood often lived into their 50s or 60s. Life expectancy varied widely based on factors such as social class, geography, and health conditions.
