3,000 years ago they put together the astrological signs. And things have, um, well shifted since then, the Earth and the Sun in relation to the stars.
Some of us are no longer under the signs we thought they were! I am no longer a Pisces. I am now an Aquarius. I don't know if I'm happy about that! And don't even ask me about Ophiuchans.
See if you've been switched HERE.
