What was the life expectancy of people in ancient India?

In our exploration of ancient India, we discover that people generally lived shorter lives, with life expectancy ranging from 20 to 30 years. This is primarily due to the harsh conditions they faced, including disease and warfare. However, if one survived past infancy, their chances of living a longer life increased significantly. It is also fascinating to note that ancient Indian scriptures mention individuals living for hundreds of years, although these are likely metaphoric or spiritual interpretations. Regardless, such short life expectancy is a stark contrast to the modern-day circumstances.
