This book goes to show you the dangers of the information age where there is so much information about you available that anyone with the knowhow and the desire could know just about everything about you and with a few tweaks, can change your entire history. It also raises some interesting concepts about love relationships. It seems everyone is searching for a conceptualized "perfect" mate that they have in their mind, which is probably someone made up of ideas garnered from Hollywood and other such sources. In reality, the perfect mate is someone you never really pictured. You just know them when you meet them.
I thoroughly enjoyed this book about a company that has figured out that with enough information about a person (historic, physical, mental) you can use computer simulations to find the perfect mate. The author introduces a lot of information about psychological testing (I assume it is all correct) and presents everything in terms that the simplest layman can understand.
I enjoyed this book slightly more than the author's previous work Utopia, which was pretty good in its own right.
