The question of women ageing faster is quite true. So yes, the problem will come up when 10 years down the line the 40 year old woman (consider Simi in this case) may be busy with her job, a kid(probably) and so her attention will be divided between the two mostly and she would not be able to ???adjust to a normal active partner at 32.
The same is the case when like in the usual norm older man marries younger woman also. A man at 40 is busy building his career in this demanding era where he has to prove his worth in his office. If he had a wife who is 8-10 years younger to him, the woman would be 30-32 and would be in the prime of her youth wanting to lead a normal active family life. What happens if the husband is busy with his tensions at office and is not able to meet the needs of his wife. Even then problems arise.
in traditional society, woman is not vocal about her physical needs though it does exist and bothers her a lot. Even then the family life is shattered and eventually in some cases head for a divorce. People who continue to put up with these so called sexually related issues, don't get a chance to discuss, since the issue is taboo. And the woman is given a warning by her so called family...men are like that. You need to adjust. So the chapter is closed.So problems relating to failed marriages with respect to individual sexual preference and activity will exist whether the guy or the girl is older.
Olden days this scientific concept of older guy younger woman was preferred for several reasons...
Man alone went to work and was the breadwinner. So an unpaid domestic servant who also caters to his sexual needs is preferred.
Men took decisions being older and the patriarchal lineage.
Women with their permanent oocyte reserves give birth to normal children when they are between 22-28 years of age.
But in men spermatogenesis is monthly and hence the tendency to have lesser abnormalities in your offspring (children).
With advancement in science in relation to infertility and assisted reproduction, all these fertility related issues cropping from the capability of producing healthy children based on age is taken care of.
So either which way, procreation issues based on which our ancestors had set such principles can be fairly dealt with.
Then what else is the issue?
In this story line, Manju, being younger than her husband and Anita being younger than Anuj has not lead to any appreciation with respect to taking important decisions and living a harmonious life. These couple cannot actually tell what's going on in their spouse's mind. But the lead pair in spite of age differences can understand each others thoughts and pain even without seeing each other's face.
So there is no practical problem in guy being younger. They would be better off if there is no societal interference.
