Optimism: Astrology

Astrology is the study of the influence that distant cosmic objects, usually stars and planets, have on human lives. The position of the sun, stars, moon and planets at the time of people's birth (not their conception) is said to shape their personality, affect their romantic relationships and predict their economic fortunes, among other divinations.
What most people know about astrology is their "sign," which refers to one of the 12 constellations of the zodiac. This is a form of sun-sign astrology, which is the astrology upon which newspaper horoscopes are based. It is probably the simplest form, because nothing more than the date of someone's birthday is needed to generate a sun-sign horoscope. Many astrologers will tell you that this form of astrology is so simplistic that it produces very limited results. Blind faith in astrology is not worth. But yes, 50% of the times, the astrological predictions turn out to be true.
