546. The lifespan of people there is for the most part thirty years. Those beyond that age are said to be unteachable, so that the spirits do not venture to reprimand and chastise them, for they say they know these things as well as the spirits. Therefore, because they are not flexible and docile like their young people, spirits are less desirous of speaking with them. Moreover, it is of the Lord's Providence that they do not live beyond those years, lest the population grow too large. For their offspring are multiplying, because famine and thus scarcity of food does not withhold them from the sense of obligation to have children, as on this earth. Therefore they are brought together [in marriage] in their earliest youth, nor do they want anything more than to have children, caring little for the other delights, as they are here called. They are eager only for offspring.
