Astrology is bullshit but fun to learn about. It's a bit like fortune telling in that regard - total bollocks but entertaining anyway.
I'm a Pisces and a Dragon. I'm supposed to have trouble with my feet (WHICH I DO) because I work on them all day. OMG, WHAT AN AMAZING COINCIDENCE, I MUST GO OUT AND BUY SOME MYSTIC CRYSTALS. Pisces are also supposed to be unlucky people, as their problems tend to compound and then come to a head all at once. Their fortunes do as well, but even when things are going well they're always on the lookout for the next crisis.
