Question: what is the maximum age difference between wife and husband?
Answer: Ideally the wife should be 10 to 20 yrs younger than the husband for them to age together as man ages slowly compared to woman due to hormonal reasons. Also, the popular opinion is to follow the rule of half plus seven. E.g, if husband is 40 years old ,then ideal age of wife should be (1/2 of 40)+7 = 27yrs.
