How long does it take to digest gum? Not 7 years....

Remember when your grandmother used to warn you not to swallow your gum because it would stay in your system for seven years?  Well, Grandma, you were wrong.  The theory that it takes gum seven years to be digested is just an old wives tale.  In fact, it only takes a couple of days at most.  While it is not necessarily healthy to swallow chewing gum, it also won't kill you--or stay inside you for seven years.
