Two "houses of living" can be seen. Each floor represents a decade. 500 years ago (left), the ages at death were broadly scattered. About one fourth of all newborns did not even reach the end of their first year of life. The average age at death was - statistically calculated - about 30 years. In reality, nearly no one died at this age. The swings upwards and downwards were very significant. In the meantime, the ages at death focussed and the average doubled or tripled. Today (right), it is about 75 years.
