HN is not a good place to ask questions on Anthropology, so I'd encourage you to read primary source materials. You have a common misconception about human longevity. The "average" lifespan of humans was only 30 -40 years because very young humans would frequently die from disease or accidents. Humans have been capable of living to 70+ years for many millenia, it was just rare. 50 yearold humans were not rare though. The average is low because of infant and childhood mortality.
