The life span of a fortune teller is only 49 years old _ is it credible to calculate the life span of 47 years old?

40-49 years old, ancient people have a low life expectancy, and those over 70 years old are old, and they get married early, basically around 20 years old, so it is late to have a son after 30 years old, which is called late childbirth; After forty, there are very few children, called old children. Now numerology changes with people's life span, and some terms are also changing. Late birth generally refers to after 40 years old. Arriving late means that you have no son when you are young, only a daughter, or you have no children when you are young, and you have a son or a child when you are old. Therefore, being late is a very happy thing.
