How to convince parents that women are older than men?

The latest scientific research shows that the older a man is, the older a woman is, which is scientific, because women will be more mature, more supportive of men's careers, know what they should do at home, and will not be too willful, so they let their husbands concentrate on their work outside, so there is a saying that women are mistresses, holding gold bricks in their hands. Moreover, the average life expectancy of women is several years longer than that of men, which is also one of the reasons. There is also a woman who is good for the harmony of husband and wife's life. Women's desire for husband and wife life reaches its peak after their thirties and forties, while men's peak is in their twenties. If women are older than men, it will be more harmonious.
