The short lifespan included many who died at birth or by the time they were like 5 years old from disease or malnuitrition. If you eliminate that segment, it was speculated that the caveman could have a lifespan of about 65-70 years. Now, this is still shorter than the current average for modern man which I recently heard was something like 78.1 years, but not substantial like the common misperception of 25-35 years of age.
