Divorce has become an accepted norm in the US and many other countries as well. Even in countries where divorce was rare, it is growing at an alarming rate. Divorce is costly, both in emotionally and financially. Not everyone wants a divorce. When we get married, we all have the intention of being married for life. Till death do us part, right? A lot of people are puzzled by their divorce. "We love each other," they all proclaimed. Love alone is not enough. After a few years of marriage, love and endorphins will eventually wear out. There is no more sugarcoating. What used to be cute and adorable qualities now become an annoyance. How many times have we heard this: "The noise she makes when eating used to be adorable. Now it annoys the hell out of me." In Southeast Asian countries, parents of the groom often seek the advice of a psychic or fortuneteller to see if their future daughter-in-law is compatible with their son as well as with them. I have seen many cases in which the bride has to walk through the back door of the groom's house because the soothsayer claims that she is not compatible with her mother-in-law and can bring harm to the family. There are many other examples that would seem bizarre to the Western sensibility. However, there is certain truth to this compatibility requirement. Although the psychic uses his mystical psychic power to determine whether they are compatible, we can use science to help determine compatibility between 2 people who are about to spend their lives together. This book will teach you a simple Homo sapiens alphabet system to understand the different physical types and their inherent behaviors. Once you understand the differences in physical types and their inherent behaviors, you will know which type is and isn't compatible with each other. Love combining with physical type compatibility will increase your chance of a successful long-lasting marriage.
