Eu não sou muito ligada em astrologia, mas achei o assunto interessante. Até mesmo porque tenho atualmente 29 anos e tenho passado por uma pequena reviravolta.
In astrology, the Saturn return is an alleged phenomenon which is described as influencing a person's life development at 27 to 29 or 30-year intervals. These intervals or "returns" coincide with the approximate time it takes the planet Saturn to make one orbit around the sun, i.e. 29.4 years. It is believed by astrologers that, as Saturn "returns" to the degree in its orbit occupied at the time of birth, a person crosses over a major threshold and enters the next stage of life. With the first Saturn return, a person leaves youth behind and enters adulthood. With the second return, maturity. And with the third and usually final return, a person enters wise old age. These periods are estimated to occur at roughly the ages of 28-30, 56-60 and 84-90.
