In many Asian countries marriages are arranged by elders in the family as "love" as it is practiced in the Western countries is perceived as a temptation into sin and possible loss of honor (pre marital sex) especially for young girls. As a result of these beliefs elders usually take a lot of trouble to match love horoscopes before negotiating or consenting to any marriage proposal. There are also mediators, or people who work as match makers who match love horoscopes for a living. While a few decades ago this aspect was of paramount importance, today many young people consider the time used to match love horoscopes a total waste. In fact in some places, bribing the mediators to match love horoscopes favorably to please the elders is quite common.
Even if the younger generations is Asia do not the matching of horoscopes very seriously today, the first thing that most youngsters who are in love would do is to match love horoscopes and see whether they are compatible, even if it was just for fun.
