Hi Lisa,I have to answer questions based on the research we have. The research about astrology is not very encouraging. Ken Wilbur, a well-known philosopher and writer, describes a study of 300 astrologers who were asked to do charts for people as part of a study. The findings were that the charts didn't describe the people any better than a random chart.
The other research I've read in the past that compared fraternal twins' lives and other populations you would expect to have similar life paths show no consistent correlations with astrological signs. If you Google "astrology studies" and read some of the literature that isn't coming out of astrologers themselves or astrology organizations, you'll see that the studies are pretty conclusive in showing there are no correlations between an astrological chart and a person's life.
I seem to recall reading something about some athletes having a correlation between their signs and their abilities, but I don't recall anything more about the studies.
Love and peace, Craig
