When big age difference with the partner does not matter!
It is very interesting to note that many times people develop a relationship with either people much older than they are or with people much younger than they are. This applies to individuals of either sex. Though this kind of relationship is not very common, we do find such relationships in our society. The question is what drives such alliances? In some poor families where the poor parents almost sell their young daughters for material gains in the guise of a relationship. That is purely exploitation. In some other cases it could be exploitation by muscle power. In other cases it is purely by mutual attraction and consent.
I would like to exclude such cases driven by exploitation and focus on relationships developed between two mature individuals with mutual consent for the current scope of study. Most likely, in such cases, the decisions are likely to be emotionally driven than anything else. Obviously, Moon should play an important role here. Also, such people break the norms of the society, go ahead and demonstrate that they are different. Undoubtedly, one could imagine the influence of Rahu in such situations. I also wanted to look for the combinations for love marriage showing up as these relationships are usually developed between them rather than arranged. Another key player would be Saturn. Saturn is the planet that represents aging.
