Research has revealed that the father’s age increases up to 47 weeks when a daughter becomes a father. This research has been done by the Jagiellonian University of Poland, after which it is claimed that daughters are behind the father’s longevity. It means to say that daughters increase the age of the father.

It has also been seen that the more daughters the father has, the greater his age. The research university claims that it studied more than four thousand people during the research. In which two thousand mothers and as many fathers were involved. This research is believed to be the first of its kind in the world. After the report of the research, there is a debate about this research all over the world.

It was told in the research that the age of fathers who gave preference to sons has been seen less. Similarly, a study in the American Journal of Human Biology has shown that the birth of a daughter may be good news for the father, but it is not so for the mother. But this study gives the same conclusion about sons as well. At the same time, research has also found that having a daughter increases the efficiency of the father.
