I'm guessing Chinese Zodiac counts as astrology. Every time my mum goes at me for whatever reason, she occasionally refers to my being born in the year of the whatever, and goes they're always slack, and what not. I always end up saying that there's more statistical variation within each year than there is between each one, let alone people twelve years in age apart sharing a common flaw or future. Though, I have to admit, it does describe my character quite well. Coincidence of course.
