The Stone Age people died – in respect to present – very early. Poor hygiene, illnesses, bad nourishment and burden of labour lead to an average life expectancy of 20–25 years. Many children already died in their first 4 years. In the Bronze and Iron Age, the adults already got a bit older: 30–45 years old. But as well here, ¼ of all newborn babies died and about half of all newborns did not survive to become an adult. Due to birth complications many young women died already when they were not even 20 years old. However, there were people who turned 50 years old or even older. From the Roman Times, stories are known of people being 70 or even 80.
