"Nobody was considered "old" at 30 in prehistory, just as 30 year-olds aren't considered "old" among modern day hunter-gatherers, or in the Old Testament, where humans were allotted 70 years (three score and ten). People who lived beyond childhood often–even typically–lived into their 60s and 70s in prehistory. The evidence for this is overwhelming, and well known to specialists in anthropology, primatology, and archaeology."
