How long did people live in 400 BC?

In 400 BC, life expectancy varied significantly based on factors such as location, social status, and overall health conditions. Generally, people might have lived into their 30s or 40s, but many infants and children did not survive past early childhood, which skewed average life expectancy lower. Those who made it to adulthood could potentially live into their 50s or 60s, especially in more favorable conditions. However, records from that time are limited, making precise estimates challenging.
