When Should I Cancel My Credit Card?

Dear Savvy, Is it a good idea to cancel a credit card you are paying off instead of waiting until you pay it off entirely?

Before you make the decision to cancel a card, make sure that canceling it won't negatively affect your credit score. Don't cancel a card that you've had for a long time because you want to maintain the longevity component of your credit history.

Earth gives off a relentless hum of countless notes completely imperceptible to the human ear, like a giant, exceptionally quiet symphony, but the origin of this sound remains a mystery.

Now unexpected powerful tunes have been discovered in this hum. These new findings could shed light on the source of this enigma. The planet emanates a constant rumble far below the limits of human hearing, even when the ground isn't shaking from an earthquake. (It does not cause the ringing in the ear linked with tinnitus.) This sound, first discovered a decade ago, is one that only scientific instruments - seismometers - can detect. Researchers call it Earth's hum Earth's Hum

Group of Seven

Group of Seven (G7), international organization officially established in 1985 to facilitate economic cooperation among the world's largest industrial nations; summit meetings of the member nations began in 1975. Members are Canada, France, Germany, Great Britain, Italy, Japan, and the United States. Representatives of the European Commission also have attended G7 meetings since 1981. The G7 discusses and coordinates its members' actions on economic and commercial matters and works to aid the economies of other nations. The leaders of the G7 nations meet annually in member countries. The Group of Eight. (G8), which consists of the G7 nations plus Russia, was officially established in 1998, although Russia began participating in some G7 meetings earlier in the 1990s. G7 nations continue to meet without Russia on certain issues. Emerging nations had long complained that their interests were not addressed during the G7 meetings; these concerns resulted in the first meeting (1999) of the newly formed Group of 20. (G20), with the G7 nations plus Argentina, Australia, Brazil, China, the European Union, India, Indonesia, Mexico, Russia, Saudi Arabia, South Africa, South Korea, and Turkey.
