2,000 years ago, the average lifespan of humans varied significantly depending on various factors such as geographic location, social status, access to healthcare, and overall living conditions. In general, life expectancy in ancient times was much lower compared to today due to factors like limited medical knowledge, higher rates of infectious diseases, and harsh living conditions.
In ancient Rome, for instance, the average life expectancy at birth is estimated to have been around 20 to 30 years. However, this number can be misleading because it includes a high infant mortality rate. Many infants died in their first year of life, which significantly skewed the average downward.
If an individual managed to survive childhood and reach adulthood in relatively good health, their life expectancy would increase. People who lived into their 40s, 50s, or even older were not uncommon, especially among the wealthier and more privileged classes.
It's important to note that life expectancy figures from ancient times are estimates based on historical evidence and archaeological findings. As we go further back in history, the available data becomes scarcer and less accurate. Therefore, the numbers mentioned above are rough estimates and may vary depending on the specific time and location being considered.
