I guess that's more than is warranted, since we're actually talking about a very long period. But this is what they're concluding for the bodies from this site in any event.

However, one should add that they study's authors are not putting it down to anything beloved of the Paleo movement, but to dirty water:

According to the UGR anthropologists, life expectancy barely reached 30, "since they suffered from many problems of malnutrition and severe gastrointestinal disorders, due to drinking the polluted waters of the Nile".
