I was never a great believer in astrology (in fact I view it as pseudo-science of the worst kind), but I was none the less amused to find that I am not (a member of?) the star sign I thought I was.
Apparently there are thirteen signs to the zodiac, not twelve. I am not the Sagittarian I beieved myself to be, but Ophiuchan.
How cool is that? I can ignore the horoscopes even more thoroughly now!
