The old rule of determining a socially-acceptable age difference in partners goes something like this: half your age plus seven (40 = 20 +7 = 27) to define the minimum age of a partner and your age minus seven times two (40 = 33 * 2 = 60) to define the maximum age of a partner.
Hereof, how much of an age gap is OK?
According to the rule, you divide your age by two and then add seven to calculate the “socially acceptable” minimum age for a partner. For example, if you’re 32, you can date someone as young as 23 while remaining in the realm of “socially acceptable,” according to the calculation.
Furthermore, do marriages with large age gaps last?
The findings also suggest that marriages with large age gaps are less resilient in the face of economic hardship when compared to spouses who are similarly-aged. … Women are also particularly dissatisfied when they’re married to older husbands and particularly satisfied if they’re married to younger husbands.”
