Why in acient period people live more than the life span ???
If you are refering to the Old Testament's claims of extraordinary 900+ year lifetimes (e.g. Methuselah, Adam, Noah),there is some dispute about tha accuracy of the Sumerian translations that led to those figures. See
http://en.wikipedia.org/wiki/Methuselah
You will find some fundamentalist speculation about longer ancient (biblical) life spans there. There are references to God's having reduced the maximum lifetint to 120 years after the Flood as some sort of punishment for human misbehavior.
There is also a dispute about a watery dome that once covered the earth in Old Testament claims, preventing harmful sun rays from affecting our environment... that would dramatically raise the average death rate.
If you still don't know the answer just g.O.o.g.L.e it and you'll get it!Or ask in W (Y)ahoo! answers
In the ancient period, people did not necessarily live longer than the average lifespan we have today. It is a common misconception that people in ancient times lived significantly longer, but scientific evidence does not support this claim.
To understand why this misconception exists, it's important to consider a few factors:
1. Inaccurate documentation: Historically, birth and death records were not as comprehensive or accurate as they are today. In many cases, it was difficult to determine the exact age of a person at the time of their death. This often led to overestimating the age of individuals, giving the impression that people in ancient times lived longer.
2. High infant mortality rates: In ancient times, the infant mortality rate was much higher compared to modern times. Many children died at a very young age due to lack of medical advancements, poor sanitation, and prevalent diseases. When recording life spans, the deaths of these infants were sometimes not taken into account, leading to higher reported average lifespans.
3. Smaller population and fewer elderly individuals: The population size was significantly smaller in ancient times compared to today. This meant that the number of elderly individuals was relatively low. With a smaller sample size, it is easier for outliers—people who live exceptionally long lives—to skew the average lifespan.
4. Differences in lifestyle and healthcare: Ancient civilizations did not have access to modern healthcare, nutrition, and sanitation practices. These factors contributed to a higher incidence of diseases, infections, and other health issues, leading to lower overall life expectancies.
However, it is worth noting that some individuals in ancient times did live long lives due to various factors such as genetics, a healthy lifestyle, and a combination of favorable circumstances. But as a whole, the average lifespan was not significantly longer than what we have today.
To summarize, the idea that people in ancient times lived longer is primarily a result of limited documentation, higher infant mortality rates, smaller populations, and differences in healthcare and lifestyle.
