For gaining more information about people. It also gives you more psychological insight. My last tutor (who sadly died...) was a psychologist, he said my knowledge already reached Psychology III(third year of psychology in collage!!!) Besides the fact that I don't know anything about chemicals.... It's also fun to use, you can determine how the next couple of months are going to be for you. If you just got a new aquaintance(SP?), and know their sun and moon, you have information of how to deal with them, or even know how to become pals. Did you know Madonna made a song about Astrology? (I just heard it on the radio... maybe I should make a thread about that...)lol
