CANCER (June 21-July 22): The Old Testament book of Leviticus presents a long list of forbidden activities, and declares that anyone who commits them should be punished. You're not supposed to get tattoos, have messy hair, consult oracles, work on Sunday, wear clothes that blend wool and linen, plant different seeds in the same field, or eat snails, prawns, pigs, and crabs. (It's OK to buy slaves, though.) We laugh at how absurd it would be for us to obey these outdated rules and prohibitions, and yet many of us retain a superstitious loyalty toward guidelines and beliefs that are almost equally obsolete. Here's the good news: Now is an excellent time to dismantle or purge your own fossilized formulas.
