I think this doesn't mean applicable to us who are born before 2011. As what I have read in some articles, the change of earth rotation causes the change of zodiac signs, therefore, who will be born today will have to apply the new zodiac signs. If you are the type of person who are so dependent on horoscopes, you will be confused because you will be looking two horoscopes. For example, my zodiac is Virgo, in the new zodiac I am now Leo... if I'm so fond of horoscopes, which will I follow? Of course I'll follow the best one. This may create confusion to other people and most especially to the new generation.
