Sunsigns are not meant to tell all about a person. They are but one aspect of an astrological schematic of an individual. To determine details regarding one's future, past, or origins time and place of birth must be ascertained. Then, the positions of all planets at the birth moment must be calculated. Most supermarket "astrology" charts are based solely on sunsigns and cannot be regarded as complete in any fashion. There are numerous ways to get a more detailed account. One way is a computer program (disk) which can calculate the details for you. This cannot, however, replace the human factor of intuition and should not be relied upon as your only informational resource. Computer programs are interesting and fun, but they do not replace people nor should they.
